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.

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.

Retaining the Arduino UNO form factor shield compatibility and 5V operating voltage yet powered by a 32-bit Cortex-M4 and a 3-to-16x increase in clock speed, memory and flash storage.

The Arduino Uno R4 is to have a Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, and there are "no plans to discontinue the ... shield compatibility, and 5V operating voltage as its predecessor,” ...
