=NULL ###Serial Error check | perl<->arduino

While developing project ideas I investigated communicating with an Arduino board using perl. Evolving some scripts I found online, I incorporated some simple error checking which I thought people might find useful. The process also raised questions relating to error checking on computational machines.

Galvanic Skin Response (GSR) sensor

A sensor to measure changes in skin resistance which can be hooked up to an Arduino board. I kept finding partial descriptions of how to make one of these so decided to pull together all the snippets in one place to make life a little easier.

The following circuit is a simple proven design that won't win any awards for accuracy, but it does 'work', with one key limitation in that the contact points tend to corrode if used over long periods of time, though these can easily be refreshed with a quick rub of sandpaper.
