@DieterHolz Don't we need a passive buzzer? as the active one will make a sound, as soon as it's powered? This one would be recommended: https://tinyurl.com/35v9cdj6

We need a buzzer that can change the volume (and still produce a "nice" sound).

Actually, I don't know if we have to use a passive or an active buzzer for that.

Yeah, i've read into it. We can use one of them: Buzzer1 https://www.berrybase.de/sensoren-module/audio-schall/ky-006-passives-buzzer-modul?c=89

Buzzer2 https://www.berrybase.de/sensoren-module/audio-schall/ky-012-aktives-buzzer-modul

While we vary with the input-Voltage, we can control the sound-volume
