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.

Making an Arduino-powered automatic trash bin that opens and closes the lid for you is a great way to get started with electronics and sensors. If you're looking to make your garbage can even ...

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.

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.

With the integration of the RA4M1 processor from Renesas, the UNO R4 adds a 32-bit microcontroller with up to 16x the clock speed, memory and flash storage. Based on an Arm Cortex-M4 core, the RA4M1 ...

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 ...
