Danke für die sehr gute Beschreibung. Kann man in die Schaltung ein Drehpoti einbauen um die Lautstärke zu regeln? Wenn ja, wo?

Thank you for the very good description. Is it possible to build a rotary potentiometer into the circuit to control the volume? If yes, where?

I did it the digital way:
The service 'triggerhappy' can execute commands with key combinations, see https://blog.gc2.at/post/hotkeys-zuweisen-ohne-x11/ and https://github.com/GrazerComputerClub/Raspjamming-Image/blob/master/etc/triggerhappy/Pi-XO.conf

GPIO inputs (switch connected) are assigned to keys, see https://blog.gc2.at/post/gpio-tasten/ and https://github.com/GrazerComputerClub/rpi-boot/blob/master/Pi-XO.txt

This feature is used for my Pi-XO game console project, see https://github.com/GrazerComputerClub/Pi-XO

The analog way:

The potentiometer is connected between Output and Speaker.

Hallo, vielen Dank für die Erklärung und Schaltung.

Ich habe vor an einen aktiven also mit stromversorgten Lautsprecher einen Pi Zero anzuschließen.

Dafür brauche ich ja keinen Audio-Verstärker, da der Lautsprecher ja schon selber aktiv (verstärkt) ist?
