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
Connection Diagram
Source Code
Code 1：
Code 2：
Note:
If you drag the source code we provided to the Microsoft MakeCode Block editor https://makecode.microbit.org/#editor
Click the icon 
, you can check the frequency of each tone as follows:
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.
