Today we have microcontrollers, wonderful micro-miniaturized wonders that combine a computer with the ability to directly connect to lights, alarms, motors, solenoids, sensors, and other physical things. In fact, this whole concept now goes by the catchphrase physical computing. I mention this because physical computing plays directly into building robots. That’s why microcontrollers ...
