Hi,
I'm looking for a way to connect a buzzer to gpio and control it by dzvents or blocky, someone have an example for this

All depends on the buzzer type, as you did not post it specs it's a wild guess. Raspberry GPIO are 3.3v, so you probably need an external transistor circuit to connect the buzzer. Depending on the current the buzzer draws, you probably need an external powersupply also.

Well the electronics part I will manage, looking for how to handle a gpio pin trough dzvents or blocky. Want to use it for arm and disarm signal for my robotic home alarm with zwave devices
