Application Ideas

<syntaxhighlight lang="c"> const int ledPin = 12; // 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(20);
 digitalWrite(ledPin,LOW);

} </syntaxhighlight>
