Arduino Fan Control // 2-Wire, 3-Wire, and 4-Wire CPU Fan Speed Control and Measurement

In this tutorial I will show you how to control 2-wire, 3-wire, and 4-wire CPU fans using an Arduino. With 2-wire fans and 3-wire fans, speed control is possible using an N-channel MOSFET and PWM. With 3-wire fans and 4-wire fans, it is possible to measure the fan speed using an Arduino input and a pull-up resistor. With 4-wire fans, speed control is possible directly with a PWM Arduino channel without the use of a transistor or MOSFET.

Look forward to a future video where I will use these fan control techniques to control the fan on a DIY hovercraft. Please subscribe to my channel and help me reach my goal of 1,000 subscribers by the end of 2020. Thanks for watching!
