The Adafruit Circuit Playground Express board has lately become my go-to board for prototyping really quickly. Using CircuitPython and the Mu Editor, I can adjust code to make things work as I go along.
The Circuit Playground Express board is also capable of playing small sound clips. I found a howling wolf .wav file I liked. There was not enough room on the board’s memory to load the sound file. I used Audacity to downsample the sound clip to a low 16khz.
Version 2 features being considered are a Full moon detector and water bottle holder.
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.
