# buttonled.cpp

A quick demo showing how to determine whether the on-board push button is pressed or not.

    // Light an LED while the button is pushed down

    void setup() { /* nothing needed */ }

    void loop() {
      if (buttonDown())             // If button currently pressed
        ledOn(BODY_RGB_RED_PIN);    // Raise the red lantern
      else
        ledOff(BODY_RGB_RED_PIN);   // Else don't

      // Note this could have been a 'one liner'!  Like this:
      // void loop() { ledSet(BODY_RGB_RED_PIN, buttonDown()); }
    }
