/* switch
* Each time the input pin goes from LOW to HIGH (e.g. because of a push-button
* press), the output pin is toggled from LOW to HIGH or HIGH to LOW.  There's
* a minimum delay between toggles to debounce the circuit (i.e. to ignore
* noise).

int inPin = 2;         // the number of the input pin
int outPin = 3;       // the number of the output pin
int state = HIGH;      // the current state of the output pin
int reading;           // the current reading from the input pin
int previous = LOW;    // the previous reading from the input pin

// the follow variables are long’s because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
long time = 0;         // the last time the output pin was toggled
long debounce = 200;   // the debounce time, increase if the output flickers

void setup()
pinMode(inPin, INPUT);
pinMode(outPin, OUTPUT);

void loop()
reading = digitalRead(inPin);
// if the input just went from LOW and HIGH and we’ve waited long enough
// to ignore any noise on the circuit, toggle the output pin and remember
// the time
if (reading == HIGH && previous == LOW && millis() time > debounce) {
if (state == HIGH)
state = LOW;
state = HIGH;
time = millis();

digitalWrite(outPin, state);
previous = reading;
