Semiconductor components Some types that are particularly useful for BEAM robots Semiconductor components are essential to build any circuit more complex or interesting than an R / C oscillator. For purposes of part selection, I've broken these devices down into three categories: Diodes (includes LEDs and Photodiodes) BEAMbots use simple diodes for a variety of purposes, LEDs as both indicators and sensors, and photodiodes as light sensors.   Solar cells Many BEAMbots are solar-powered, and thus need solar cells to provide them with energy.   Transistors (includes Bipolar transistors, Phototransistors, FETs, and transistor packaging) BEAMbots use a variety of transistor types in a number of different functions.
