The Adafruit products compatible with MakeCode Arcade are designed such that they can clip onto a lanyard without a case. (Many cases are also designed with lanyard clips). Hence the name for PyBadge - it can be worn as a badge. This is very similar to the current "badge life" craze at conventions to make electronic badges.
But what if you could customize the display with your own design. This guide will get you started with Microsoft MakeCode Arcade to just that. The steps are laid out slowly and carefully to ensure beginners can follow along and not assume prior knowledge of programming or MakeCode Arcade.
For advanced users, see this guide for more customizable features using CircuitPython.
