const int sensorPin = 2; // the number of the sensor pin
const int ledPin = 13; // the number of the LED pin
int sensorState = 0; // variable for reading the sensor status
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(sensorPin, INPUT); }
void loop(){
// read the state of the sensor value:
sensorState = digitalRead(sensorPin);
// if it is, the sensorState is HIGH:
if (sensorState == HIGH) {
digitalWrite(ledPin, HIGH);
}
else {
digitalWrite(ledPin, LOW);
}
