// We will be using D2 to control our LED
int ledPin = D5;
// Our button wired to D0
int buttonPin = D6;
void setup()
{
// For input, we define the
// pushbutton as an input-pullup
// this uses an internal pullup resistor
// to manage consistent reads from the device
pinMode( buttonPin , INPUT_PULLUP); // sets pin as input
// We also want to use the LED
pinMode( ledPin , OUTPUT ); // sets pin as output
}
void loop()
{
// find out if the button is pushed
// or not by reading from it.
int buttonState = digitalRead( buttonPin );
// remember that we have wired the pushbutton to
// ground and are using a pulldown resistor
// that means, when the button is pushed,
// we will get a LOW signal
// when the button is not pushed we'll get a HIGH
// let's use that to set our LED on or off
if( buttonState == LOW )
{
// turn the LED On
digitalWrite( ledPin, HIGH);
};
if( buttonState == HIGH ){
// otherwise
// turn the LED Off
digitalWrite( ledPin, LOW);
