Just follow the schematic diagram shown below to complete your own Arduino circuit board! About the ATmega 328 chip It is a good idea to use a socket for the chip. If the chip is pre-programmed, you ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

This little circuit board is at the heart of many DIY projects, from robotics to art projects and just about everything in between. But what on Earth is Arduino, anyway? What makes it so versatile?

At the heart of the Arduino Due is an 84MHz Atmel CPU, based on ARM's Cortex M3 Architecture, which is capable of being the brains inside your own flying drone or homemade 3D printer.
