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.

Arduino is one of those boards that has become synonymous with hacking and making. Since its introduction in 2005, over 700,000 official Arduino boards have been sold, along with untold millions of… ...

The best way to learn Arduino, as with any other hands-on skill, is to practice creating a project. You can find a host of ideas online, but the best resource to find Arduino projects to try is ...

Well, the name is definitely cool, but you’re probably wondering how this project works. It uses an Arduino Uno, an LCD readout, and a sonic ranging module to judge various distances.

Arduino says these additions allow for more advanced projects. Besides Wi-Fi and Bluetooth, the UNO R4 Wi-Fi has a built-in LED matrix with 96 dots arranged 12x8.

Sweden-based coder Johan Kanflo was looking for a way to make the Tiny328, which he was using in his DIY projects as an ISM radio node, more portable. Kanflo wanted a case for the Tiny328 with a ...

Sporting 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, and even a USB connection, the SainSmart UNO is ready to help you build stuff like infrared sensors, remote ...

For the micro-controller part of the project I used an old Arduino Uno development board that had been collecting dust in a drawer and combined it with a £2.50 16×2 LCD screen I had previously ...

Two new variants of the Arduino Uno development board, the lightweight Uno R4 Minima and the full-fledged Uno R4 WiFi, are each powered by a 32-bit microcontroller. These next-generation Uno boards ...
