Arduino & Raspberry Projects
Measuring Water Flow Rate and Volume using Arduino and a Flow Sensor
Flow rate and volume helps tell the amount of fluid going into, or through a particular vessel.
Arduino based Milliohm Meter with LCD display
One of the best things about being a maker is the ability to make your own tools.
ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication)
I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32.
ESP8266 based Online Weather Widget using Wemos D1
A few years back I wrote this tutorial on connected weather monitor with plans of creating a 3D printed enclosure to make it portable and easy to use.
Introduction to LoRa – Send data between two Arduino using LoRa
Selecting the right communication protocol is an important part of any IoT project as not being able to communicate with the server/device cloud quickly takes away the “I” in IoT and could lead to the ultimate failure of the project.
Video Streaming Server on ESP32-CAM
A while back, I noticed an ESP32 based Camera board called the ESP32-CAM on LCSC.com, and planned on getting one to play with but didn’t get the chance until recently when I saw a tutorial by Rui Santos based on the board.
Network Clock using ESP8266 and OLED display
There are several situations where using an RTC could adversely affect your project by increasing cost, size, time accuracy or IO requirements.
Arduino RFID Reader using the ArduiTouch MKR Enclosure
RFID based projects are one of the most popular Arduino projects out there and we have also built a couple of them here too, but I recently came across an RFID access control project by hwhardsoft that was built using the ArduiTouch MKR enclosures.
Battery (Lithium, NiMH, NiCd) Capacity Tester Using Arduino
The increased interest in IoT and electric automobiles around the world is driving an increase in the use of Lithium-Ion/Lithium-Polymer/NiCd/NiMH batteries as more devices and applications are using them, due to their high energy storage capacity to size ratio.
Isolated Gate MOSFET Driver Based DC Motor and Solenoid Driver Arduino Nano Shiled
This is an Isolated gate driver-based N channel Mosfet Arduino Nano shield based on Si8261ACC, which can be used in various applications like DC Motor driver, solenoid driver, led driver, bulb driver and heater driver, with 3A fast switching diode provided across the output for an inductive load which protects the circuit from back EMF.
Isolated CAN BUS Transceiver Arduino Shield
The module described here is an isolated CAN Transceiver module.
How to use STONEtech STVC035WT-01 intelligent TFT LCD module with Arduino
Displays have over time, emerged as one of the best ways to drive user interactions on any device.
