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 ...
Microcontrollers like Arduino are designed to control small loads, such as LEDs or sensors, directly from their output pins. However, these pins can only supply a limited amount of current (typically ...
