Welcome to Sound sensor repository
1. Description of Pin
1-1 Position of pin
2-1 Position of Potentiometer
It is necessary to adjust the potentiometer of the sound sensor module to optimize the sensitivity.
3.Power indicator light
3-1 Position of indicator light
This power indicator will illuminate when the module is powered normally.
4.Switch indicator light
4-1 Position of indicator light
When the sound level reaches the set threshold, this indicator will be illuminated, indicating that the module has recognized the sound in the current environment.
5.Sound receiving head
5-1 Position of receiving head
The module receives sound by it, and the sound needs to face the receiver to obtain the best experimental results.
6-1 Position of MCU
This master chip of module.
Hardware connection: (The definition of the pin can be changed in the program by yourself)
1.Connect to Arduino board.
2.Connect to Micro:bit board.
We will provide Arduino, Micro:bit driver source code.
