NEW GUIDE: Desk Calculator with @adafruit @CircuitPython

There’s a new guide in the Adafruit Learn System: Desk Calculator with CircuitPython.

Consider the humble calculator. Now just an app that you always have with you on your telephone, an electronic calculator used to be a technological marvel.

In this project, you’ll build your own calculator with an Adafruit Feather RP2040, 128×64 OLED display, and 20 keys. Optional 3D printed parts like an enclosure and even the keycaps themselves make for a sharp presentation. Make it your own by customizing the code, or use the hardware for your own MacroPad-inspired project.
