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.

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.

Hello everyone ! I'm working on a project and I would like to know if an arduino uno with an arduino uno motor shield R3 can run the GRBL ? I'm able to upload GRBL in the arduino but i don't know if I ...

The Elektor design from a few years ago was essentially an "evolved" take on the Arduino Uno R3 board, with an identical form factor as the Uno but based on the ATmega328PB-AU (see the "B"). As ...

The UNO R3’s 8-bit architecture remains highly relevant for teaching the fundamentals of computer science. In terms of project applications, the UNO R4 WiFi board is well-suited for creative projects ...

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