Hi LMR. I have already made a robot, as you may know, but all I did (on the physical/electrical side of things) was plug a few cables into the pre-made servo ports on the Board of Education, as my copy of Electronics for Dummies told me to do. I read the entire thing, but they explained a few things in a way I didn't understand. Like the names for stuff, and what each means. Until now, I thought voltage was a measure of battery capacity. I FAIL, I know. I've sorted it out, so now I know about amps and volts, but I have a couple technical questions regarding electricity.
