For more info see https://ograblog.wordpress.com/2019/10/09/attaching-a-cpu-fan-to-a-rpi-running-ubuntu-core/
Make sure to connect the snap interface for the correct GPIO that your fan is attached to (see https://pinout.xyz for correct mapping)
snap connect pi-fancontrol:gpio pi:bcm-gpio-14
The snap allows a few configurations to be set
Pick a different GPIO to swithc the fan on/off (do not forget to use the above connect command to enable access to this changed GPIO)
snap set pi-fancontrol gpio=23
Set the temperature threshold (in degrees celsius) at which the fan turns on
snap set pi-fancontrol threshold=40
Set the interval (in seconds) at which the temperature gets scanned
snap set pi-fancontrol interval=60
Indeed you can set all these also from a gadget.yaml file in the ```defaults:``` section.
Generate an embeddable card to be shared on external websites.
