Introduction
To learn the fundamentals of electricity, circuit design and micro computing we were given a robot kit in my Art-74 class. The kit has a simple IC along with a couple photo diodes. When turned on, the amount of light received to each diode determines the resistance on each motor load. Therefore, when calibrated properly the robot shall automatically seek light. I named him (it’s a he) ALF-1, or, Autonomous Light Follower One.
