So you have a nifty display like a bright Charlieplex LED or NeoPixel matrix powered by MicroPython, but what if you want to write text on it? Most MicroPython display modules only give you basic pixel drawing commands so it’s very cumbersome to draw text yourself pixel by pixel. Luckily there’s a handy new MicroPython bitmap font module you can use to draw text on any pixel-based display! This module shows some of the power of MicroPython–a single module can work with any pixel display because of MicroPython’s dynamic language features. In this guide you’ll learn how to use a bitmap font rendering module with pixel-based displays like the Charlieplex LED matrix or simple LED backpack matrix.

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.
