Before we can build Simple Bots
, it is important to have a rudimentary understanding of how electricity works (or does not). Electricity comes in two forms, AC (alternating current), which is like the power that comes from a wall socket, and DC (direct current), which is like the power that comes from a battery. In the Simple Bots eBook
, all of the electricity for bots will be coming from batteries. So, I will only be explaining DC (direct current) electricity in this Instructable.
