'another option on the approach with the mpr121 that avoids polling'

I like that post #11 suggestion @SimonGAndrews and although I haven't measured, I believe that technique also extends battery life, as Javascript isn't continuously executing as a result of the setInterval duration.

That is a useful insight! The device I'm working on will be plugged in via USB the whole time, but future projects might be portable... thank you!
