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 ...

Relay-Interfacing-with-Arduino 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, ...

This project involves controlling a relay using a Light Dependent Resistor (LDR) and an Arduino. The system detects the ambient light intensity using the LDR sensor. Based on the detected light level, ...
