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 ...

So, this cause the fan unable to move even if the temperature exceed the threshold temperature. Solution 1. Connect the GND of the battery to the GND of arduino – common GND. If you are using a 5V ...
