In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

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

The new $49.99 Snapino kit (recommended for ages 12 and up) adds an Arduino UNO circuit board (a tiny but real computer) to the mix, giving Snap Circuits its first true programmability.
