rial - Reading states of multiple toggle switches

/13/2008Isn't the ATmega169 on the butterfly a modern AVR where you can toggle any pin by writing 1 to the corresponding PIN register? Yes, it has the pin toggle option for the PINx registers. Regards,

Ready, Set, Oscillate! The Fastest Way to Change Arduino

Arduino: Toggling Outputs by James Lewis. D id you know it is possible to toggle the state of a Arduino OUTPUT pin using a single line of code? It’s true! It’s also possible to use digitalRead() on an OUTPUT pin. Assuming pin 13 was set to output, this single line of code will cause the LED to change state (or flash) each time it is called:

Arduino- Reading a Momentary push button and changing state

On the other hand, if you actually want to measure what the electrical state of a LED is, that is not directly or solely driven be a dedicated LEDPIN, then you need to setup a dedicated pin in INPUT mode and perform a digitalRead() on that pin measuring the state via a suitable circuitry.

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
