By far the best book for all kinds of electronics is "the art of electronics" by Horowitz and Hill. There is not a lot of "what is electricity" (try a good encyclopedia).

I have had great success with black tape on many different light colored backgrounds but I wasn't using discrete components for the sensors and emitters. Instead, I used Omron EE-SY313 amplified infrared photosensors, and plugged them right into the (...) (27 years ago, 17-Apr-97, to lugnet.robotics.handyboard)
