An arduino-controlled relay for automatically switching AC voltage supply on and off at user-defined time intervals and durations. Included are the build notes. Part of the Open Science Framework ...

This project controls a relay module using an Arduino, providing both automated timer-based operation and manual override functionality via a button. The system is designed for applications where a ...

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 ...
