  1. In my last tutorial I created a Weather Station using Arduino and NodeMCU using DHT11 or DHT22 temperature and humidity sensor and displayed it using an OLED Display. In this tutorial, I am going create a Peg-Box using the same board but with a little bit of twist. In this setup, I am going to send the Temperature and Humidity readings to my Raspberry Pi based home server and store it in a MySQL database. The data can then be viewed using PHP and Google Charts, on a Mobile Phone or a PC connected to the home network. Circuit Diagram The setup is very simple. The temperature and humidity sensor sends the collected data to the NodeMCU on pin D3. NodeMCU then sends the data over WiFi to the Raspberry Pi, which is then saved in the MySQL database. The Yellow LED, which is the status indicator flashes every second and is connected to D6 pin of the NodeMCU. The Blue LED connected to pin D5, lights up when NodeMCU sends the temperature and humidity readings to the database. If you are planning to install this box somewhere inside the house, then you can also add an OLED display and display the readings on it. The Board So, this is how my board looks like in 2d and 3d. There are 3 breakout boards in this 100cm x 100cm assembly. Each board can be used with either Arduino or NodeMCU and DHT11 or DHT22 sensor or sensor module. Temperature and humidity readings can be collected using either a DHT11 or DHT22 Module or by using one of these sensors with a 10K resistor. The bottom section of the board is for the OLED display. The attached gerber is bit different from what you see on screen. I made some modifications in the final version and moved the sensors a bit far from the microcontrollers. Component Assembly Lets start by soldering the female pin-headers to the board. The pin-headers will house the NodeMCU in it. Next, lets soldered few more pin-headers for the LEDs, DHT11 sensor and the OLED display. Before installing the circuit in the peg-box, lets hook up the OLED Display and make sure everything works as expected. Boom, nailed it. The Code The code starts by including all the libraries and by defining all the constants and variables that will be used throughout the program. Then there are two functions SendIamAlive() and SendTemperatureAndHumidity() which sends heartbeat and the data read from the temperature sensor to the database server. The ReadDHTSensor() function reads the data from the DHT11 or DHT22 sensor. In the setup section we first setup the WiFi and then send a SendIamAlive() message to the server advising that it is back up and running. Then in the loop section the microcontroller send a heartbeat every minute using the SendIamAlive() function and if the time elapses it sends the humidity and temperature data using the SendTemperatureAndHumidity() function. The White LED flashes every seconds and the Blue LED turns on when the device sends the temperature and humidity data to the database server. MySQL So,the data sent by the NodeMCU over WiFi is saved in the MySQL database hosted on a RaspberryPi 4. Here you can see, the microcontroller sends the data every 30 minutes (you can change the frequency) which is then saved in the MySQL database. The data saved on the Pi's MySQL database can then be used to generate various different types of graphs either by using google charts or any other 3rd party application. It totally depends on you how you want to present it. 3D Design Now, lets look at the design of the peg-box. Using freely available pallet planks, I designed the body of the box. The pallet planks I am using are 160cm x 9cm x 2cm (length, width and thickness). So, the rest of the measurements will be based on that. The top bit of the peg-box will house the microcontroller and the sensors in it. Putting it on the top prevents the electronics from adverse climatic conditions. The back bit will stick to wall and hence we don't need to cover it up. You can either put the pegs straight in the front bin or throw it to the top bit, from where it will slide down to the front bin. The sliding design with an opening in the front will prevent rainwater from accumulating inside the bin. This mechanism will keep the bin dry throughout the year. Woodworking Using 2 hammers I am dismantling the pallet. My aim is to reuse all the nails used in building this pallet so that, I can use them in building my project. After that, I sanded the pallet planks to give them a nice and smooth texture. Then using a chop-saw or a hand-saw I extracted all the pieces of wood required for building this project. As mentioned earlier, my pallet plank are 9cm wide and hence, all the onscreen measurements are based on that. Final Assembly Using wood-glue I am joining all pallet planks used in making the box. I got a bit too excited and accidentally deleted one of my recordings. So, I am using 3D animation to show you guys how I joined the two sides of the box. I used a plywood board to created the base of the bin. I glued few cylindrical wooden sticks on the roof of the box. To be very frank these sticks changed the entire outlook of the peg-box. Coloring Since my aim is to install the peg-box outside the house, I have to make sure that I apply multiple coats of paint on the box to avoid the pallet wood from rotting. I applied 3 coats of paint on the entire setup and insulated all the holes that I found using wood putty. So, this is how it looks like. The electronics bit will stay hidden under the roof of the box. Ha ha, Don't worry, I will obviously insulate them and make them weather-proof before installing them on the wall. Installation Now the next thing you need to do is to find a spot where you want to install this unit. I am installing this near my clothesline, however you may want to install it in your pantry or behind a door or something like that. It totally depends on how much space you have and where you want to install it. I am using metal frame hangers to hang this on the wall. Place the unit against the wall, and using a pencil mark the points where you want to drilling the holes. Now, using a hammer drill, drill the holes in the wall. Then, put the wall plugs in the wall and then use a screw driver to install the screws. Alright so, that's it. This unit is now all set to hold all my pegs in it. Demo So, this how my final setup looks like. Do comment and let me know if there are any scopes of improvement. Thanks Thanks again for checking my post. I hope it helps you.

  2. If you can't find a Raspberry Pi, why not make your own? The StackyPi, an RP2040-based board with a Raspberry Pi Zero tiny size, will be delivered by SB Components, the firm behind this Kickstarter. This isn't the first time we've seen anything like this; we recently covered the Red Robotics Pico 2 Pi, which adds GPIO capability to the RP2040-powered Raspberry Pi Pico module. That board, on the other hand, was more of an adapter, whereas this one is a fully functional unit. The StackyPi has two rows of 20 male header PINs ripped out for total GPIO access. The StackyPi is compatible with a broad selection of Raspberry Pi HATs thanks to its GPIO support. The only requirement is that the assistance be designed by the end-user. In addition to the GPIO, SB Components has included a micro SD card connector, 64MB of onboard flash, and a few surface-mounted buttons. A micro-USB port is used to power the StackyPi. StackyPi specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 264KB SRAM Storage – 8MB (64Mbit) SPI flash, MicroSD card socket USB – 1x Micro USB port Expansion – 40-pin GPIO header with GPIO, I2C, UART, SPI, etc… mostly compatible with Raspberry Pi header (3.3V I/Os) Misc. – Reset and Boot buttons Power Supply- 5V via Micro USB port Dimensions – 65 x 30 mm (Raspberry Pi Zero form factor) The StackyPi has two rows of 20 male header PINs ripped out for total GPIO access.

  3. Couple of months ago, I bought a "Raspberry Pi Pico" to get some hands-on experience of it and to create some amazing projects using it. But since then, it has just been sitting on my desk, collecting dust. Today after a very long wait, I finally have decided to create a short video tutorial to show you guys how to get started with the Raspberry Pi Pico. Topics Covered In this tutorial, I am going to discuss: 1. What is a Raspberry Pi Pico? 2. The technical specifications of the board 3. How to program Pico using C/C++ and MicroPython a. Programming Raspberry Pi Pico using "Arduino IDE" i. Preparing the Arduino IDE ii. Loading the Blink Example iii. Demo b. Programming Raspberry Pi Pico using "Tonny Python IDE" i. Installing MicroPython on Pico ii. Installing Tonny Python IDE iii. Loading the Blink Example iv. Demo 4. Difference between Raspberry Pi Pico and Arduino 5. Advantages and Disadvantages of this board What is Raspberry Pi Pico? Raspberry Pi Pico is a low-cost microcontroller. It can be used to control other electronic modules and sensors same as any other microcontroller. Pico is not a Linux single board computer, rather it is a microcontroller like Arduino. Since, its a microcontroller it doesn't come with all the overheads that a computer brings and hence consumes much less current. actually it is more like Arduino than Raspberry Pi. Pico is not a rival of Raspberry Pi Zero, it actually can work in conjunction with the regular Pi's. Pico is breadboard friendly and has 40 GPIO pins operating at 3.3v (20 on each side). It has a Dual-Core ARM Cortex M0+ processor. Pico's brain - the RP2040 microcontroller chip is designed by Raspberry Pi in United Kingdom. It can be powered either via the micro USB port, or via the VSYS GPIO pin by providing voltage between the range of 1.8V to 5.5V. Technical Specifications of Pico Raspberry Pi Pico is absolutely different from all other Raspberry Pi models. Pico is one of the first microcontrollers to use the RP2040 "Pi Silicon" processor. It is a custom "System on Chip" (SoC) developed by the Raspberry Pi team in UK which features a dual core Arm Cortex M0+ processor running at 133 MHz, 264KB of SRAM and 2MB of flash memory for storing files on it. Specifications: - Microcontroller: RP2040 designed by Raspberry Pi in the UK - Processor: Dual-Core Arm Cortex-M0+ processor, flexible clock running up to 133 MHz - Input power: 1.8 - 5.5 V DC - Operating temperature: -20°C to +85°C - Dimensions: 51.0 x 21.0 mm - Onboard Sensors: Temperature Sensor - Memory: 264KB of on-chip internal SRAM and can support up to 16MB of off-chip Flash 2MB on-board QSPI Flash (Adafruit's Feather RP2040, features 16MB of storage) - GPIO: It has 40 GPIO through-hole pins also with edge castellation - 26 × multi-function 3.3V GPIO pins, which includes 3 analogue inputs (The Analog inputs is something other Raspberry Pi's lack. They use variable voltages to connect to devices like a potentiometers, joystick or a LDR) - 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels - 8 × Programmable I/O (PIO) state machines for custom peripheral support that can offload many kinds of timing-critical processes from the CPU - Other Features: - 1 × Contains 1 × USB 1.1 controller and PHY, with host and device support - Accurate clock and timer on-chip - Low-Power sleep and dormant modes - Accelerated integer and floating-point libraries on-chip - Works with Windows, Mac, Linux machines and Raspberry Pi Computers - Provides drag-and-drop programming using mass storage over USB The one biggest disadvantage of the Raspberry Pi Pico is that there is no WiFi or Bluetooth on it. ESP32 and ESP8266 which you can buy for similar price comes with WiFi and Bluetooth (ESP32). Surely we can add wireless connectivity via external components, however that would require a little bit more knowledge and experience to get it working. Since Pico is not a computer, we need to write our codes on a different machine using an external application and then "flash" the code onto the microcontroller over USB. Pinout Diagram: Here is the top view of the pinouts on the Raspberry Pi Pico. The pin-labels are on the bottom side of the board. How to program Pico using C/C++ and MicroPython Pi Foundation officially supports MicroPython and C/C++, however high-level programming language like CircuitPython (A fork of MicroPython created by Adafruit), and Drag and Drop Python Editor like Pico Piper which adds further enhancements and can be used to program the Pico boards. Programming Raspberry Pi Pico using Arduino IDE Python and C/C++ are both great for programming Picos. However, being able to program a Pico just like an Arduino would help us to integrate the Pico into the Arduino ecosystem. One of the best reasons to do this is because of the availability of libraries to integration of modules, sensors, and other complex stuff without having to write the entire code from scratch. i. Preparing the Arduino IDE To start, let go to Tools > Boards > Boards Manager and search for "Pico", select "Arduino Mbed OS RP2040 Boards" and hit the install button. Connect the micro USB cable to the Pico and then press and hold the "BOOTSEL" button before plugging the USB cable into the computer. Release BOOTSEL once the drive RPI-RP2 appears on your computer. Now, go to Tools > Port and you will now be able to see the number of the COM Port. ii. Loading the Blink Example Go to Files > Examples > Basics > Blink and click on Upload, this will load the code to the Pico board. iii. Demo After the IDE finished uploading the code, you will see the Pico's onboard LED blinking. You can now use your Pico like an Arduino and program it using the Arduino IDE. Programming Raspberry Pi Pico using Tonny Python IDE You can program your Pico using MicroPython by connecting it to a computer via USB and then dragging and dropping files to it. i. Installing MicroPython on Pico Installation of MicroPython on Pico requires a "UF2" file to be copied onto it. A UF2 file is a "binary data file" which contains a program that can be transferred from a PC to a microcontroller, such as an Arduino or Pico circuit board. To load MicroPython on Pico: 1. Download "MicroPython UF2 file" from the link provided in the description below. 2. Connect the micro USB cable to the Pico and then press and hold the "BOOTSEL" button before plugging the USB cable into the computer. Release BOOTSEL once the drive RPI-RP2 appears on your computer. 3. Drag and drop the UF2 file onto the RPI-RP2 volume. 4. Your Pico will reboot. That's it, you are now running MicroPython on your Pico. ii. Installing Tonny Python IDE To write code and save files to Pico we are going to use the "Thonny Python IDE". Thonny comes with built-in Python 3.7, so just one simple installer is what you need to learn programming. To get started: 1. Download and install "Thonny" free from the Thonny website for your version of OS. The website's link is in the description below. Note: If you are running "Raspberry Pi OS" then Thonny is already installed on it, but may need to update it to the latest version sudo apt update && sudo apt upgrade -y 2. Connect the Raspberry Pi Pico to your computer. Then, in Thonny go to Tools > Options and click on the "Interpreter" tab. From the interpreter dropdown list select "MicroPython (Raspberry Pi Pico)". The port dropdown menu can be left to "automatically detect the Pico". Click "OK" to close. 3. A Python Shell called "REPL" (Read, Eval, Print, Loop) will popup to show that the Pico is connected and working. iii. Loading the Blink Example 1. Click in the main editor pane of Thonny and enter the following code to toggle the onboard LED. from machine import Pin, Timer led = Pin(25, Pin.OUT) timer = Timer() def blink(timer): led.toggle() timer.init(freq=2.5, mode=Timer.PERIODIC, callback=blink) 2. Click the "Run" button to execute the code. 3. Thonny will ask whether you want to save the file on "This computer" or the "MicroPython device". Choose "MicroPython device". Enter "blink.py" as the file name. Make sure you enter ".py" as the file extension so that Thonny recognizes it as a Python file. iv. Demo You should now see the onboard LED switching between on and off until you click the Stop button. Difference between Raspberry Pi Pico and Arduino * Before Raspberry Pi Pico, Raspberry Pi has always been know for their single board computers. However, in 2021 Raspberry Pi Foundation stepped a few steps forward and launched the Raspberry Pi Pico giving a head-to-head challenge to Arduino and all other board based microcontrollers. * Arduino was first introduced in 2005 and since then Millions of Arduino Units have been sold in the market. Compared to that, the response Pico received after its initial launch in 2021 is absolutely mind-blowing. * Both units are made for automating applications that don’t involve human intervention. * Pico can be used alone or in combination with Arduino for Automation and AI purposes. * Both modules are different in terms of power consumption, value, functionality, and price. * Pico boards come unsoldered however Arduino comes pre-soldered or unsoldered. * Pico module supports MicroPython and C/C++, while Arduino codes are written in C/C++ using Arduino.IDE. So which one to go for… Pico or Arduino? Advantages and Disadvantages Now lets have a look at the Pros and Cons of this microcontroller board. Advantages: * Raspberry Pi Pico is cheap, very small, and easy to use microcontroller * Pico is a dual core device coupled to a high-performance bus matrix, which means its both cores can give you the full performance concurrently * Pico consumes very low power * Pico is a breadboard friendly * Pico can be programmed using C/C++ and MicroPython * Pico can be programmed using Arduino IDE * Pico has 26 × multi-function 3.3V GPIO pins (23 Digital + 3 Analogue) * Pico comes with 8 x Programmable IO (PIO) and 2 x Analog Inputs * Pico boots quickly and doesn’t require a safe shutdown Disadvantages: * Pico completely lacks WiFi and Bluetooth without any add-ons * It lacks the GPIO markings on the top side of the board * The board comes unsoldered so you will have to solder the header pins or surface mount it to use it in your project * GPIO pins are 3.3V, which could be seen as a disadvantage, however devises designed for 5V can still be used with 3V via a voltage divider or a logic level converter. * Pico still uses micro-USB port. While many other microcontrollers have moved to USB-C, Pico is still coming with the micro-USB port If you have a Windows, Apple, Linux or even a Raspberry Pi, then you are already well in your way to program the small, cute, and gorgeous Raspberry Pi Pico in your next project. I bet, there must be a lot of project ideas going in your mind, so get your supplies and start coding. And, what are you waiting for??? Thanks Thanks again for checking my post. I hope it helps you.

  5. AI Smart agriculture control Device Abstract: Agriculture is the broadest economic sector and plays an important role in the overall economic development of a nation. Technological advancements in the arena of agriculture will ascertain to increase the competence of certain farming activities. Smart Farming is a farming management concept using modern technology to increase the quantity and quality of agricultural products. Farmers in the 21st century have access to LoRa, soil scanning, data management, and Internet of Things technologies, web. Our device focuses on the measurement of physical parameters such as soil moisture content, nutrient content, automatic irrigation, pH of the soil and automatic sent notification phone application that plays a vital role in farming activities. Keyword: Agricultural innovation, IoT, LoRa, Power Management, ARM, Data Management Introduction: Smart farming based on IoT technologies will enable growers and farmers to reduce waste and enhance productivity ranging from the quantity of fertilizer utilized to the number of journeys the farm vehicles have made. In IoT-based smart farming, a system is built for monitoring the crop field with the help of sensors (light, humidity, temperature, soil moisture, etc.) and automating the irrigation system. The farmers can monitor the field conditions from anywhere using smart app. IoT-based smart farming device is highly efficient when compared with the conventional approach. The applications of IoT-based smart farming not only target conventional, large farming operations, but could also be new levers to uplift other growing or common trends in agricultural like organic farming, family farming (complex or small spaces, particular cattle and/or cultures, preservation of particular or high quality varieties etc.), and enhance highly transparent farming. Now, let’s discuss the major applications of IoT-based smart farming device that are revolutionizing agriculture. Hardware: Soil Sensor: The Soil Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content). Simply insert this rugged sensor into the soil to be tested, and the volumetric water content of the soil is reported in percent. Temperature sensor (DHT 11): Measure the Temperature and humidity Photoresistor (LDR): Check day or night position LoRa ARM development board : This is a low power single board computer inbuild Wi-Fi, LoRa connectivity also has Digital and analog pins. Smart Agriculture Device Features: 1.This device no need external power (inbuild 5-volt Power bank & solar cell), 2. real-time Soil Moisture sensor measure the soil and sent data to the Server, 3.Temperature, photoresistor measure the weather condition. 4. Both way communication (device can send notification & received command from web or app) 5. Dual control (Device ca run manual mode and automatic mode). 6. Dual communication (LoRa and wi-fi mode) System Hardware Implementation: First configure the FreeRTOS on EFB-REV1 board after successful configure of operating system we need configure GPIO library(J-Tag) to access the its GPIO. Install 5-volt solar cell and power bank for powerup the device 24x7. Soil Sensor connected to analog pin of A0, DTH11 connected to A3, Photoresistor connected to A6. Analog sensors measure data and sent via wireless media. EFB_REV1 development come with LoRa, Wi-fi also Bluetooth, for our project we used Wi-Fi and LoRa. For Wi- fi communication need a wifi receiver module which receive and sent sensor data to the cloud server. Another hand implemented the device for loRa communication (data send rang up to 5km), here we need a loRa receiver to receive and sent sensor data to the cloud server. Wi-Fi and LoRa connective protocol of our smart agriculture device uses depend on different location & situation. Firmware & Application software implementation: Application Software: Here we used cloud server to store the data, and help of Rest API sent the command to the device. Device firmware has two measure function (i) Manual mode: In manual mode device will work, user pre set value of the sensor in device using web or smart app. (ii) Automatic Mode: In automatic mode device sent the sensor value to cloud server and machine learning algorithm take decision according the data. Conclusion Thus, the IoT agricultural applications are making it possible for ranchers and farmers to collect meaningful data. Large landowners and small farmers must understand the potential of IoT market for agriculture by installing smart technologies to increase competitiveness and sustainability in their productions. With the population growing rapidly, the demand can be successfully met if the ranchers, as well as small farmers, implement agricultural IoT solutions in a prosperous manner.
