A simple Raspberry Pi fan controller using Node-Red

The 5V DC fan is controled with a MOSFET and turned on and off with GPIO17

A tri-colour LED is connected to GPIO24 and GPIO25, but not needed for the temperature control

Updated layout (Version 2) with a SOT-23 MOSFET and a Fan on LED.

You can’t perform that action at this time.
