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 ...
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 ...
This project demonstrates how to control four relays using an ESP8266 (NodeMCU) and the Arduino IoT Cloud. The relays can be toggled locally via physical switches or remotely using a cloud-based ...
