    Ce buzzer actif fonctionne bien mais il n'est pas plus puissant qu'un buzzer de base

    Arduino project buzzer

    As said by "gabiel" the labels are wrong. Connect +voltage to the "-" connect the ground to the "S". You will hear a high pitched buzzer sound. It's probably possible to adjust the frequency by adjusting voltage or using a controlled sinus, but I haven't done that yet. I didn't use the middle pin, I don't know what it is used for. Using the buzzer for my Raspberry Pi project now and it works good!
