Improved version of the soldering iron controller for Hakko 907 iron. To simplify building the controller, LCD screen is implemented.

Use the IO Expander and Relay Expander with the Arduino to control up to 65,280 relays!

This code performs FFT with good accuracy.

On this simple tutorial, we will explore how to discover colors using an Arduino and the TCS 3200 sensor, displaying it on an LCD.

Measure rotation speed (RPM) with Optocoupler and Encoder disk and Arduino - Quick and Easy!

We implement CAN Bus communication with MCP2515 module to communicate between two Arduino for sending temperature data from DHT

Step by step approach is followed so that any hobbyist or design engineer can have a better understanding of the basic concepts.

Make your own mini oscilloscope at home. It’s simple and easy to do!

Need fast cheap laser rangefinder for your Arduino project? You can use a laser tape measure for this!

The soldering iron controller based on arduino that implements PID method to keep the temperature of the iron.

This is my 4th tutorial on how to drive a RELAY (not a relay module) with an Arduino.

A simple to build, but very sensitive electromagnetic field detector.

FreeRTOS, simple, easy, robust, and optimised for Arduino IDE. Using FreeRTOS Semaphores to share and protect physical resources.

In this project, you can measure typically up to 48V. It is recommended to use Arduino digital voltmeter as “0-48V DVM”.
