Abstract

Microcontrollers are “embedded” inside some other device. Microcontrollers are dedicated to one task and run one specific program. The program is stored in read-only memory (ROM) and generally does not change. Microcontrollers are often low-power devices. A microcontroller has a dedicated input device and has a small LED or LCD display for output. A microcontroller also takes input from the device it is controlling and controls the device by sending signals to different components in the device.
