This ebook covering most of the Atmel AVR ATmega328P microcontroller features and its aimed for the beginners, hobbyist, or anyone who wants to learn and.

In this project we are going to use both the Arduino IDE and Atmel AVR Studio to program the AVR ATMega168 microcontroller, therefore you could learn to use these well known Integrated Development Environment (IDE) to program the project.

In the first part we have accomplished a basic DC motor controller tasks i.e.

Literally breadboard is mean a piece of wood (board) we usually use to cut the bread, this term later used by many of earlier electronics experimenters to descript the board they used to construct and connect all the electronics components on the piece of wood board.

Using the TIMER peripheral as the basic timing, we could easily develop a stopwatch and display it to the 8-Digit seven segment numeric LED display.

Thanks to the Maxim MAX7219 chip which enable us to interface this 8-Digit seven segment LED display much easier using just three wires of the SPI (serial peripheral interface) to display the hour, minute, second, and hundredth of seconds to the 8-Digit seven segments LED display.

As more and more wireless devices has been developed in this past few years, in the year 2012 we are going to explore some of popular wireless devices available on market.
