What debouncing technicques do you know?

Try this method, I already used in my projects and worked fine.
The only issue is that you will need to use a switch with 2 contacts.

I always use the software method. Polling the pins in a loop or using a Timer interrupt. The timer interrupt will also provide the debouncing delay.

The main advantage of a timer interrupt is that you need ONLY 1 routine, running in background and you button states are available everywhere, when you need.

That's What Ernie suggested too
