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

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

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.

For example, I would want to statically allocate that buffer by either passing it into the SSD1306 driver class, or by making the driver class a template so that the compiler can size it ...

The Arduino development board has grown in popularity over the last few years and has spawned a myriad of interesting projects such as auto-lacing shoes, The EyeWriter 2.0, and the Mobile Dance Stage.

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.

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 ...

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.

Renesas’ SVP, Chris Allexandre, said, “We are honored to collaborate with Arduino on their iconic UNO product line. Despite the challenges of this intricate project with a rich legacy, our 5V 32-bit ...
