I am new with arduino stuff and Cylon, so sorry if this question sounds silly.
I have attach a laser receiver sensor to my arduino board and I'd to read its state change with Cylon.
I try to look up on the available GPIO drivers and end up trying 'button'. The event I know is 'on push' which seems will be triggered only when it state change from 0 to 1. But I need also the opposite, which is from 1 to 0.

How do I get the event? Thank you.
