Microcontrollers are electronic devices that are programmed to perform a set of instructions. They complete any given task as often as prompted until they are reprogrammed. You can find them everywhere, from lights that automatically turn on when it’s dark to garage door openers that respond to sensor input to open, close, or reverse direction.
Arduino is a versatile microcontroller that can easily be programmed. It was originally designed as a low-cost device to provide easy access for non-technical people to create devices that are interactive. Arduino has an interesting history as an open-source hardware and software company.
