This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

Here we are making a simple project with Arduino which uses three basic components that are IR Sensor, Relay Module and DC Motor. Here we will interface IR sensor with Arduino to control DC Motor.

Waveshare ESP32-S3-Relay-6CH is a 6-channel WiFi and Bluetooth relay module based on Espressif Systems ESP32-S3 wireless microcontroller that also supports RS485 control and comes with headers taking ...

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...
