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 thresholdvalue=400; //The threshold to turn the led on
3
void setup() {
4
pinMode(ledPin, OUTPUT);
5
}
6
void loop() {
7 int sensorValue = analogRead(A0); //use A0 to read the electrical signal
8 if(sensorValue>thresholdvalue)
9
digitalWrite(ledPin,HIGH); //if the value read from A0 is larger than 400,then light the LED
10 delay(200);
11 digitalWrite(ledPin,LOW);
