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 ...

Arduino UNO R4 Minima Both Arduino UNO R4 boards retain hardware compatibility with the UNO form factor and 5V operating voltage meaning you can keep using existing shields. They also add HID support ...

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 ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

This Program is for Arduino Uno R3 microcontroller to control the RGB LED such that it cycles between the following states automatically: 1. LED off 2. LED red colour on. 3. LED green colour on. 4.

The two boards are powered by 32-bit microcontrollers: the basic Uno R4 Minima; and the Uno R4 Wi-Fi. Both boards are in the standard form factor, shield compatibility and have a 5V power supply like ...

Changes: Dual operation on two boards is no longer possible, but the channel range has been increased from 32 (40) to 64 (80) if two boards / chips are to be used The Arduino SPI class is not included ...
