Hello everyone. This is the first tutorial in our AVR tutorial series. in the last tutorial we came across a term called microcontroller. Now we are going to explore one of the microcontroller family called AVR. This microcontrollers are developed by atmel company. Atmel develop a wide variety of microcontrollers from small to big so that user can choose any of the microcontroller according to his application. For more details on AVR microcontroller types click here.
In this tutorial series we are going to use atmega8 microcontroller. As I have already said that it does not matter which microcontroller used choose all the basic principle behind each and every microcontroller remains same.
Atmega8 microcontroller is shown below.
It is an 28 pin IC(Integrated circuit). every microcontroller needs power therefore out of these 28 pins, at least two pins are for giving power to the microcontroller. arduino microcontroller can control many devices, many sensors therefore some of the 28 pins are used to communicate with the outer world, these pins are called input output pins or GPIO (general purpose input output) pins. Some pins of the microcontroller are used to communicate with other digital devices. This is the reason why a microcontroller has so much pins. The complete details of at mega 8 microcontroller is given in a document called its data sheet you can download the data sheet of at mega 8 microcontroller by clicking here.
Just have a look at the data sheet, don't worry if you do not understand anything from it, this is the reason why I am creating my tutorials. let's move forward, so we have seen that make it microcontroller its pinout and its data sheet.
So now we have a microcontroller, next you will need some hardware. By which AVR microcontroller can communicates with our PC or laptop. in my next return I will show you which hardware can be used and how it can be used. see you then keep smiling.
