Touch sensor example

The touch sensor is connected to D3 and we attach an LED to D13

Code

[c]

#define TOUCH_SENSOR 3 //the touch sensor is connected to D3

int led = 13; // pin for the LED

void setup()
{

pinMode(led, OUTPUT);
pinMode(TOUCH_SENSOR, INPUT);
}

void loop()
{
int sensorValue = digitalRead(TOUCH_SENSOR);
if(sensorValue)
{
digitalWrite(led, HIGH); // turn LED on
while(digitalRead(TOUCH_SENSOR) == HIGH);
digitalWrite(led, LOW); // turn LED off
}
}
