We’re going to explore some of the User Interface (UI) elements available through displayio by creating a basic calculator. We’ll be letting CircuitPython handle the actual calculations and we’ll be concentrating on the input, output, and logic.
The PyPortal is the perfect device for setting up as a calculator with the touchscreen and large display.
In this guide we turn the PyPortal into a calculator using displayio User Interface Elements. If you want to see a Calculator created from scratch in Python, be sure to check out our guide.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
