In this video we are going to control a 12v pc fan with a transistor to cool down the raspberry pi and pidrive.

Raspberry pi pwm fan control 12v. Hi im fairly new to the electronic world and i recently bought a raspberry pi i made a perspex case for it and i still had a 12v fan laying around. In the meantime ive found another 4pin pwm fan from another brand just to see if its something specific with my fan but still no luck. It controls 3 fans via pwm that ramps up fan speed based on temperature and has real time rpm reading.

It measures the cpu temperature and adjusts its speed automatically to keep the temperature constant. Control a dc fan. Im trying to stray away from the expensive industrial world in my home automation projects namely the plc.

However these fans are usually pretty noisy and many people plug it on the 3v3 pin to reduce the noise. At least im able to control the fan speed with pwm through a transistor directly on the 12v line of the fan. Raspberry pi pidpwm 12v fan controller just for fun project.

In this video we will build a variable speed fan for a raspberry pi. Many cases for raspberry pi come with a little 5v fan in order to help cooling the cpu. Pwm regulated fan based on cpu temperature for raspberry pi.

I had many many project ideas for this neat little computer. These fans are usually rated for 200ma which is pretty. Anyway thanks for your help appreciate that.

Upload the following python program to the raspberry pi in order to test the fan control from the gpio. Yeah its strange im sure this should work. We also will learn a few things about pulse width modulation pwm pid controllers mosfet transistors and even a little bit of magic.

Also if you like these videos consider subscribing for more and dont forget to. For that i wrote a little program that you can find here in the comments.
