In this video I'm demonstrating how to build a simple Arduino on a breadboard, based on Atmel Atmega8/168/328 microcontroller.
When I build my Arduino projects usually I don't need the whole Arduino board and all of it's functionality. In many cases I use only basic input and output pins and that's why I assemble a simplified version of Arduino.

When connecting your Arduino to a power supply or a battery make sure that you connect the red jumper wire to the positive terminal and the blue one to the GND. There is no protection against reversed polarity and you may blow something up.

The circuit diagram for this project is available on my website:
electronfun.com/project_1.php

My build is based on:
arduino.cc/en/Main/Standalone
