LED backpacks are bright and beautiful LED displays with a built-in controller chip that makes them super easy to use. These displays come in all sorts of varieties, like matrices that are a grid of LED pixels or segment displays that can show numbers and characters. Because these displays use LEDs they’re bright and easy to read–perfect for showing simple measurements, time, basic graphics, and more. And now you can use LED backpack displays with MicroPython and a LED backpack MicroPython module! This guide explores how to use LED matrix, 7-segment, and 14-segment quad alphanumeric displays with MicroPython.
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.
