Description
This keyestudio passive buzzer is fully compatible with micro:bit control board.
It is mainly composed of a passive buzzer without oscillation circuit. It cannot be actuated by itself, but by external pulse frequencies.
Different frequencies produce different sounds. Even can code the melody of a song.
There are total 6 rings on the module. Note that two G rings, two V rings and two S rings are connected. G for ground; V for 3V; S for signal pin(0 1 2).
When using, connect the module to micro:bit control board using Crocodile clip line.
