I’ve built the breadboard prototype, then the first version, using only one layer (which is a good version if you want to etch your own PCB). Always wanted to make the project public as an Open Hardware, but due my lack of time, I never did, until I arrive in Genova. I then decided to make a second version of the board, two layers, the ability to program the µC without removing it from the socket (for programing you will need an Arduino, FTDI or USB-to-serial cable) and some available pins for those who want’s to add more features to the board, like a temperature sensor or another kind of sensor.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
