Microcontroller
A microcontroller is like a tiny computer that controls specific tasks in electronic devices, robots, and machines. Think of it as the 'brain' that makes decisions in everyday items like washing machines, car engines, or smart home devices. When candidates mention microcontrollers on their resume, they're indicating they know how to program and work with these small computers to make devices perform specific tasks. Common microcontroller brands include Arduino, Raspberry Pi, and PIC, which are like different types of these mini-computers that engineers use to build smart devices.
