I was given an address for a library (specifically on debouncing) inputs but it doesn't appear to exist. I am assuming there are many more. Can anyone help. Thanks Rich
Try at your Arduino IDE "Tools"-""Library Manger"-Search box-debounce
In the IDE the Library Manager is found in Sketch, Include Library.

In the version of the IDE I have (1.8.7) it appears as both Sketch->Include Library->Manage Libraries... and Tools->Manage Libraries...
