Motors and Servos

Project 15: Simple Motor Control

Project 25: Servo Control

The power set-up part of these was a little intimidating, with all the resistors and the 9V battery. I'm using a servo in my first gesture, and used this power setup in my first tests, mostly because I don't know the consequences of just using the 5.5 V that the Arduino provides. I assume worst case scenario is something catches fire. Then the second worst case scenario would be that it just doesn't have enough power to turn on.
