What is a Microcontroller ?


        A Microcontroller is a small computer in which the central processing unit, arithmetic operations, set of instructions, etc are a part of it. It is equivalent to a mini computer that can store memory and can do various operations that are all imparted to it.

      Generally, we need the computer to perform various tasks but after the invention of microcontroller, there is no need for the computer to get involved in the work. Only the thing is to impart the program into the microcontroller and memory is attached to it. The microcontroller alone performs the tasks assigned to it.

             In olden days, only 8085 microcontrollers were used to travel through the moon by inserting the chip into the astronaut suit. Now we have sophisticated microcontrollers but there is no development in the space journey after the invasion of the moon rather than scoping for mars and distant planets in our solar system and even to the center of the Milkyway.

            The Microcontroller can alone run the hardware induced software run machines but whereas a microprocessor cannot run individually without the aid of memory and clock devices.
