While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

[Damian Peckett] has implemented an Apple ] [, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.

That link also contains listings of workshops using the Shrimp microcontroller. Since it appears just like an Arduino Uno you can do any of the hundreds of projects for that board.

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

The Arduino Due has a 32-bit ARM core (the Uno is 8-bit), an 84 Mhz CPU clock, 96 KB of SRAM, and more USB ports than the Uno. In short, it's a much more powerful microcontroller that can handle a ...

You need to start by purchasing an Arduino. This is actually optional. You could just purchase the ATMega328 that is the microcontroller used in the current generation Arduino Uno boards.

The Arduino Uno R4 is to have a Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, and there are “no plans to discontinue the popular Uno R3” , according to Arduino, which estimates that R4 will ...

Arduino Make Your UNO Kit lets you build your own microcontroller from scratch 11:24 am November 7, 2022 By Julian Horsey ...

The UNO R4 WiFi features Wi-Fi and Bluetooth Low Energy connectivity, while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.

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.
