Introduction to Arduino

Been using Arduino since 2009, and was recently asked to give a presentation at my University to a group of engineering colleagues on Arduino. Was wondering if anyone had some input on:

1) How you have introduced Arduino?

2) What are some of the 'good' and 'hard' questions I could expect?

3) Recommendations to peers which are interested in Arduino, but not sure where to start.

Any inputs are much appreciated.

Thanks, that's an awesome start!

Hi, Feel free to use this and anything else from my sites: What Can I DO with an Arduino?? How can I start to make interesting high-tech stuff with Arduino? Starting to learn some stuff.... A bunch of How-To for Arduino

Sorry this is not well coordinated. In my OTHER spare time...
