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 ...

int relay = 12;//connect relay to digital pin 12 of Arduino) int button = 11;//push button to digital pin 11 of Arduino(connet a 10 K resiter to Ground keep it PULLDOWN pinMode(button, INPUT);//Pin 11 ...
