I have a Pi 4B with 4GB and installed the script as described. The script also is installed properly (service runs), I also can change the settings, but the LED doesn’t work (not red, not green). When I boot up the fans runs and does never stop. When I move pin 12 the fan stops, when i release it, it starts again (but still no LED). The button has no function either.
I had installed the fan earlier on another Pi 4B 4GB, it started and stopped automatically as expeted, but the led also did not show up.
What’s wrong here?
When at least the fan worked properly (without LED) Noobs 3.2.1 (Buster with Desktop) was installed, including all updates.
Now I use Noobs 3.3 (Buster with desktop), the script is running but the fan does not stop, also the LED is off.
What can I do? I can follow instructions, can open files with “nano” but don’t know how to program.
ATM only pi-hole with unbound is running on my Pi (at least this works well).
Thanks in advance.
