Adafruit Trellis is a great system for adding backlit keys to your own projects. Trellis’ elastomer keypad acts as both an input and fully addressable LED display. You can even tile multiple Trellises together to form large, captivating displays.
Now there’s a Python library to control Trellis from any computer with Python and I2C, like the Beaglebone Black or Raspberry Pi. Follow this guide for information on installing and using the Trellis python library.
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.
