keyestudio Passive Buzzer Module For BBC micro:bit


Description

This Keyestudio passive buzzer module is fully compatible with micro:bit control boards.
Composed of a passive buzzer without oscillation circuit, it cannot be actuated by itself, but by external pulse frequencies. Different frequencies produce different sounds as well as the melody of a song.
There are total 6 gold-plated rings on the module. Note that two G rings, two V rings and two S rings are connected. G is for ground; V for 3V; S for signal pin(0 1 2).
When using it, you need to connect it to a micro:bit control board through crocodile clip lines.

Technical Parameters

  • Working voltage: DC 3.0-3.3V
  • Output signal: Digital signal (square wave)
  • Dimensions: 31mm*27mm*4.5mm
  • Weight: 2.3g
  • Environmental attributes: ROHS

Example Result

Connect well the module, then send the source code to the micro:bit main board.
If send the code 1, the buzzer will alternately make two sounds.
If send the code 2, the buzzer will play a song of Ode To Joy.
