#138 Variable Speed Cooling Fan for Raspberry Pi using PWM and PID controller

In this video, we will build a variable speed fan for a Raspberry Pi. It measures the CPU temperature and adjusts its speed automatically to keep the temperature constant. We also will learn a few things about Pulse Width Modulation (PWM), PID controllers, MOSFET transistors, and even a little bit of magic.
