Arduino enthusiasts, ... Built using the Arduino Cloud project uses a Arduino Nano RP2040 Connect together with 4 channel relay controller for I2C.

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 ...

The initial plan was to use the ubiquitous 555 timer IC to build the feeder relay module. But then I chose an Arduino microcontroller. ... Although the initial setup is centered on an Arduino Nano ...
