Touch Sensor Red PCB KY-036 Arduino Compatible

This Touch Sensor module includes an LED. Build a simple circuit that lights up the LED when it detects a touch input.

Test Code

int Led = 13; // define LED Interface
int buttonpin = 3; // define Metal Touch Sensor Interface
int val; // define numeric variables val

void setup() {
pinMode(Led, OUTPUT); // define LED as output interface
pinMode(buttonpin, INPUT); // define metal touch sensor output interface
}

void loop () {
val = digitalRead(buttonpin); // digital interface will be assigned a value of 3 to read val

// When the metal touch sensor detects a signal, LED flashes
if (val == HIGH) {
digitalWrite(Led, HIGH);
}
else {
digitalWrite(Led, LOW);
}
}
