WebJun 29, 2024 · Scanning Interval and Debouncing. By default, all the scanners in the keypad module scan their inputs at 20 millisecond intervals. This is enough time to debounce most mechanical keys, which can take quite a few milliseconds to settle down. If you have keys that need more (or less) debouncing, you can set the optional interval parameter when ...
