/* DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. */ // digital pin 2 has a pushbutton attached to it. Give it a name: int pushButton = 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 pushbutton's pin an input: pinMode(pushButton, INPUT); } // the loop routine runs over and over again forever: void loop() { // read the input pin: int buttonState = digitalRead(pushButton); // print out the state of the button: Serial.println(buttonState); delay(1); // delay in between reads for stability }
