Handheld BASIC Computer in Badge Format with the Arduino Uno

Since the new 32-bit Arduino UNO R4 has arrived, it’s time to make a glorious farewell project for the classic 8-bit UNO R3! Clem’s idea is to use all of the pins and turn it into a handheld BASIC computer, similar to a Sinclair ZX81 from the 1980s. This computer badge will use up all of the available pins and show that an 8-bit microcontroller is, in fact, a tiny computer. The badge form factor also makes it ideal for your next meetups with fellow makers. We have two in-depth bonus videos on the element14 Community about the code and PCB design for this project. You can see those videos and download all the code and CAD for free here!
