Introduction 

Grove - Touch Sensor enables you to replace press with touch. It can detect the change in capacitance when a finger is near by. That means no matter your finger directly touches the pad or just stays close to the pad, Grove - Touch Sensor would outputs HIGH also.

const int TouchPin=3;
const int ledPin=4;

void setup() {
    pinMode(TouchPin, INPUT);
    pinMode(ledPin,OUTPUT);
}

void loop() {
    int sensorValue = digitalRead(TouchPin);
    if(sensorValue==1)
    {
        digitalWrite(ledPin,HIGH);
    }
    else
    {
        digitalWrite(ledPin,LOW);
    }
