Since the new 32-Bit Arduino Uno R4 has arrived, it is time to make a glorious farewell project to the classic 8-Bit UNO R3, by using all the pins and turning it into a handheld Basic computer, quite similar to a ZX81 from the 80s! It is finally time to build a badge that uses up all the pins and show that an 8-Bit microcontroller is in fact a tiny computer! The badge form factor makes it ideal for your next meetup with fellow makers!
