Before you jump into Part 2, you should assemble some supplies:
- A soldering iron and some solder. You need nothing fancy here since you will not do any fine or complex soldering.
- A pair of wire cutters/strippers. Advice: Don't use your teeth to strip the wire.
- The electronic components outlined earlier.
Spend time exploring the Arduino site and working through some of the tutorials. Take the LED light-sensor code and see what else you can do with it. Perhaps most importantly, recruit friends to complete this project with you. It will be more rewarding (and easier for you) if there are other people involved.
