Control a fan attached to a GPIO via NPN transistor
(defaults to GPIO 14 (pin 8))
For more info see
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.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed on elementary OS from the command line. Open Terminal from the Applications launcher and type the following:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install pi-fancontrol, simply use the following command:
sudo snap install pi-fancontrol
