This object talks to the HT16K33 16*8 LED controller. It includes (x,y) pixel accessors for the 8×8 bicolor LED matrix backpack from Adafruit. You can use this object to talk to any HT16K33-controlled display e.g. all of the Adafruit backpacks. The 8×8 matrix-specifics include a line-drawing function copied from the propeller forums. But line drawing is somewhat anticlimactic on an 8×8 display.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
