Sound Sensor/Microphone Brick
Electronic brick of microphone can be connected to the analog I / O port, when speaking to the microphone, the analog value will be changed. A recorder can be made by reading and saving the analog value.
1. Plug and Play, easy to use.Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock
|PCB Size||33.0mm X 14.0mm X 1.6mm|
|Working voltage||5V DC|
|Operating voltage||5V DC|
|Compatible interfaces||2.54 3-pin interface and 4-pin Grove interface(1)|
Note 1: S for digital output port , V and G for voltage at the common collector and ground respectively
|Digital output voltage（VCC=5V）||0||-||5||V|
Connect S port of electronic brick of microphone to A0 port of Arduino, and we will use the following program to read the analog value. When the value exceeds the threshold, the LED indicator will flash.
