Re: Knock detector with sleep

Thanks, Since the main focus of the project is power saving I would probably not want to use it to pull a pin to ground since that would require keeping the pin energized during sleep state. Since I have to order a shake switch I will try it this weekend with a piezo on the interrupt and see if that...

I don't know enough about e-ink to know if a segment like that could be cut to size ...
