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.
0 to 5V output Analog Hall Sensor for Foot Controller
This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range.
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.
Proximity Distance Sensor using DRV5053 Hall effect Sensor
This is a hall sensor proximity sensor that can detect magnetic targets approaching the sensor, without physical contact with the target.
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.
Dual Forward/Reverse DC Motor Driver with Brake for Robots
This high current forward-reverse DC motor driver is built using STK681-332 IC from ON Semiconductor.
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.
4-20mA / ±10V Analog Input Module for PLC
This is an analog input module that helps to digitalize temperature, current (4-20mA) and voltage (±10V) for PLC and Microcontrollers input.
