Create a full scale tone piano using CircuitPython, capacitive touch and some cute little fruits.
This guide will introduce you to the Circuit Playground Express (CPX for short!) and CircuitPython. The Circuit Playground Express is a fantastic little board crammed full of all sorts of sensors, switches and lights. CircuitPython is an open-source derivative of MicroPython, designed specifically for use with Adafruit microcontroller boards like the CPX.
This project will teach you how to use CircuitPython to utilise the CPX capacitive touch pads, Neopixels, slide switch, and onboard speaker. Then you’ll combine them to create a rainbow-lit tone piano!
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.
