Arduino 3pin/4pin interface Electronic Brick Sound Sensor Microphone Mic Module
Descriptions: This module 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. Specifications: Brick Type Sensor Brick Brick Interface 3PIN Brick Power Supply 5V Board Size 33 × 14 × 1.6mm Parameter Min. Typical Max. Unit Working voltage 4.5 5 5.5 VDC Digital output voltage（VCC=5V） 0 - 5 V Working current（5V） - 260 - uA Frequency range 100 - 10000 Hz Sensitivity - -50 - dB DEMO: 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. 1 const int ledPin = 13; // the number of the LED pin 2 const int thres.
