New Electronic Brick Sound Sensor Microphone Mic Module for Arduino Description: 100% brand new and high quality 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. Features: Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock. Specifications: 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, N for not used pin, V and G for voltage at the common collector and ground respectively. When there is no operation, digital output is VDD; when the button is pressed down, the digital output is 0V. Electrical characteristics: 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 2 3 4 5 6 7 8 9 10 11 12 const int ledPin = 13; // the number of the LED pin const int thresholdvalue=400; //The threshold to turn the led on void setup() { pinMode(ledPin, OUTPUT); } void loop() { int sensorValue = analogRead(A0); //use A0 to read the electrical signal if(sensorValue>thresholdvalue) digitalWrite(ledPin,HIGH); //if the value read from A0 is larger than 400,then light the LED delay(200); digitalWrite(ledPin,LOW); } Package includes: Electronic Brick Sound Sensor Microphone Mic Module x 1 Payment: We accept payment through Paypal ONLY.
