Description

This keyestudio microphone module is fully compatible with micro:bit control board. It is a sound detection device, an analog signal output device.

It is mainly composed of a MIC head, a LM358D chip and a potentiometer.

When the microphone detects sound, and converts it into a voltage signal; then amplifies it through the LM358D chip.

The potentiometer is used to adjust the signal amplification.

There are total 6 rings on the module. Note that two G rings, two V rings and two S rings are separately connected. G for ground; V for 3V; S for signal pin(0 1 2).

We can work out the sound volume by reading the analog value of signal end.

When using, connect the module to micro:bit control board using Crocodile clip line.
