in the "scripted" section of the UI
, type:
ontouch{ setVar("blahblahblah",1) } onuntouch{ setVar("blahblahblah",0) #this is the "offtouch" bit }
try that..

Hard to tell what to start with without knowing the skill level of the people you are teaching. If beginners, then basic grouping etc.. as Wacov said; then add basic coding and get as far as you can with that. Just what Wacov said plus basic coding is a weeks worth of class alone!

Wish I could be there for the coding part of it...

Thanks, I forgot about that site.

That particular script sends the servo into a progressive death spin, however the @myPos should prove very useful.
