Arduino Read Digital Input Code Example

Example: arduino digital read

int ledPin = 13;  // LED connected to digital pin 13 int inPin = 7;    // pushbutton connected to digital pin 7 int val = 0;      // variable to store the read value  void setup() {   pinMode(ledPin, OUTPUT);  // sets the digital pin 13 as output   pinMode(inPin, INPUT);    // sets the digital pin 7 as input }  void loop() {   val = digitalRead(inPin);   // read the input pin   digitalWrite(ledPin, val);  // sets the LED to the button's value }
