Microphone Sensor Module with adjustable gain. Can be used to sense audio with your projects. Compatible with Arduino. Uses LM292 comparator for digital thresholding
Includes both analogue and digital outputs
int Led = 13 ;// define LED Interface int buttonpin = 3; // define D0 Sensor Interface int 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); } }
int sensorPin = A0; // select the input pin for the potentiometer int ledPin = 13; // select the pin for the LED int 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); }
