How to toggle LED on button press? - Arduino Stack Exchange
How to toggle LED on button press? You don't need a separate variable to store the state of the LED. The output pin register does that already. So you can toggle the LED simply with (or some specialist hardware) needs to handle this. This really matters when you expect a button to toggle some output pin. share | improve this answer

The variable state keeps track of the current state – on or off. If a code is received, state is set to HI. If nothing is received for 150ms, state is set to LOW .

DigitalToggle is a library for the Arduino. It provides the functions digitalToggle() and digitalToggleFast() which toggle the state of the specified digital pin by looking up the appropriate AVR PIN register for the digital pin and then writing the appropriate bit in that register, causing the corresponding PORT bit to …
