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

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

However, the only Arduino platform included is an Uno R3. You can still create different circuits with this board, though, especially if you're primarily working on beginner projects.

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

RS Components has announced the availability of the latest Arduino board that comes with WiFi wireless networking capability and more processing power than previously available. This has been achieved ...
