While this build is demonstrated using an Arduino Nano RP2040 Connect, it’ll work on any CircuitPython board with a STEMMA-QT cable or port (like Feather RP2040, ed.). We’ll demo how to sense touch, then offer a challenge and show a solution for lighting up a NeoPixel strip with different colors, based on the pad that is touched. Part of Prof. Gallaugher’s CircuitPython School & his Physical Computing university course.
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.
