Sample Code
/*
# Description:
# When you push the digital button, the Led 13 on the board will turn off. Otherwise,the led turns on.
*/
int ledPin = 13; // choose the pin for the LED
int inputPin = 2; // Connect sensor to input pin 3
void setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(inputPin, INPUT); // declare pushbutton as input
}
void loop(){
int val = digitalRead(inputPin); // read input value
if (val == HIGH) { // check if the input is HIGH
digitalWrite(ledPin, LOW); // turn LED OFF
} else {
digitalWrite(ledPin, HIGH); // turn LED ON
}
