I have a simple fan. When I plug it to GND and Vin it spins. I'd like to have the ability to turn it on / off with code. Any example will do, as long as it gets it to spin. I have a NodeMCU board, if that helps.

Depending of the type of fan you are using, two solutions exist.

  • First one, use a MOSFET to drive the FAN from you nodemcu
  • Second one, use a relay to drive the FAN from your nodemcu

Things to consider :

  • The mosfet allow you to drive the fan without mechanical part moving.
  • The relay require some transistor and feedback diode to be driven by your µc.

So I didn't have a transistor to do a MOSFET, but I did have a motor driver which I ended up using. From there it was just finding example code to use the motor driver, connecting it up and using it.
