I hate to begin any conversation with an apology but i fear i am just not good at writing. For a school project i wrote an application note for turning your door handle into a capacitive touch sensor. I ask for feedback because i would like to post this document on the internet to help others interested in a similar project. I will post my AVR code later this evening.

What happens to the touch sensor when you have been walking on carpet on a very dry day and a few KV discharge from you hand zap it?
