Simple Arduino on a breadboard - Dec 29, 2013


In this project I'm building 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 pay attention to polarity. There is no protection against reversed polarity and you may blow something up.
