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 ...

Relay control in real time using arduino and RTC. Used in Fishtank lighting, Plant irrigation. Time values specified in structure ON - OFF sequence. Also manually can override ON/OFF sequence using ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
