The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. It was first developed back in 2003 as an affordable ...

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 ...

[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.

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...

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 ...
