3-Wire Inductive Sensor and LeoStick

/* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor/serial plotter

// digital pin 2 has a PNP sensor attached to it.

int metalSensor = 2;

// the setup routine runs once when you press reset:

void setup()

{

// initialize serial communication at 9600 bits per second:

Serial.begin(9600);

// make the sensor's pin an input:

pinMode(metalSensor, INPUT);

}

// the loop routine runs over and over again forever:

void loop()

{

// read the input pin:

int sensorState = digitalRead(metalSensor);

// print out the state of the sensor:

Serial.println(sensorState);

delay(1000);

// delay in between reads for stability
