Descrição

Microphone sound detection moduleFor sound detection Module has two outputs:AO, analog output, real-time output voltage signal of the microphoneDO, when the sound intensity reaches a certain threshold, the output high and low signalThe threshold-sensitivity can be adjusted via potentiometer on the sensorConnecting to the ArduinoPin + to Arduino 5+Pin – to Arduino -Pin A0 to Arduino A0 (for analog program)Pin D0 to Arduino 13 (for digital program) Example code: Digital output int Led = 13 ;// define LED Interfaceint buttonpin = 3; // define D0 Sensor Interfaceint val = 0;// define numeric variables val void setup (){ pinMode (Led, OUTPUT) ;// define LED as output interface pinMode (buttonpin, INPUT) ;// output interface D0 is defined sensor} void loop (){ val = digitalRead(buttonpin);// digital interface will be assigned a value of pin 3 to read val if (val == HIGH) // When the sound detection module detects a signal, LED flashes { digitalWrite (Led, HIGH); } else { digitalWrite (Led, LOW); }}Example Code : analog outputsint sensorPin = A0; // select the input pin for the potentiometerint ledPin = 13; // select the pin for the LEDint sensorValue = 0; // variable to store the value coming from the sensor void setup () { pinMode (ledPin, OUTPUT); Serial.begin (9600);} void loop () { sensorValue = analogRead (sensorPin); digitalWrite (ledPin, HIGH); delay (sensorValue); digitalWrite (ledPin, LOW); delay (sensorValue); Serial.println (sensorValue, DEC);}Powered by MediaWiki Powered by Semantic MediaWiki
