INTRODUCTION to MICROCONTROLLER(AtMega32)

What is a Micro-controller?
Earlier, there was no Machine or component Which can function as a receive some input and transmit some output  by itself i.e. it will act like a human brain itself once it is initialized or instructed to do so.
First,We tried to make something that'll function the above way..

So,MICRO-CONTROLLER is a Electronic device,Which is considered to be the simplest Computer processor (Brain of the Computer). It  contains the following contents which make it highly Powerful  they are:

1. Depending on Manufacture,some Memory, few A/D converters, timers, input/output lines etc. are added.
2. Main difference from Microprocessor is that Microcontrollers have Memory where as Microprocessors don't have.
3. All the standard requirements are in some standard Packages.
4. And, Finally a simple Software able to program it,Which all can learn and use easily.    

Microcontrollers such as ATMEGA16 or ATMEGA32 are generally used for this purpose.
we are going to familiarize you with AtMega32.
Its pin diagram is                                                                                    

 Some of its properties are:
1.Types of Memory

• FLASH : In-System Reprogrammable Flash Program Memory(32Kb)
• SRAM (Static RAM) : These get copied from flash on startup  
• EEPROM : Electronically Erasable Programmable ROM

      Don't worry We will be explaining each of them later.
2.   32x8 general purpose registers
3.   32 I/O lines
4.   Serial communication port
5.   8-bit and 10 bit ADC
6.   TIMER
      and many more...
