What is a Microcontroller?

A microcontroller is a small computer and it can only perform simple task.

Microcontroller consists of :

• Processor that executes programs. Processor execute program digitally. All instruction given to the processor should be in digital form.

• Program Memory to store the program that has been compiled successfully by the programmer.

• RAM (random-access memory) to store "variables."

• IO Port to connect sensor, keypad, LED, Relay and so on.

• Timer to count the time to execute some process.
