Some BEAMbots use H-bridge motor drivers; many more use an H-bridge variant of some sort. Here’s a simple conceptual schematic: Image A basic H-Bridge has 4 switches, relays, transistors, or other means of completing a circuit to drive a motor. In the above diagram, the switches are labeled A1, A2, B1, B2. Since each of the four switches can be either open or closed, there are 24 = 16 combinations of switch settings. [...] Link [...] [...] Probably the simplest, reversible drive circuit is the H-Bridge. Some BEAMbots use H-bridge motor drivers; many more use an H-bridge variant of some sort.
