Control a fan attached to a GPIO via NPN transistor (defaults to GPIO 14 (pin 8))
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.
Choose your Linux distribution to get detailed installation instructions. If yours is not shown, get more details on the installing snapd documentation.
