Every year for the past several, I’ve made a musical ugly Christmas sweater. Welcome to the 2018 edition! I loved the llama sweater from last year, so I bought a similar llama sweater from Wal-mart to mod out this year. I envisioned being able to control my sweater with my phone, and the Flora Bluefruit LE module was the perfect component to enable this. I sprung for a new Adafruit Flora Arduino controller as well, and I reused the LilyPad MP3 player from last year. It took me a solid couple of days of prototyping to get all of the components talking to each other. I reprogrammed the MP3 player so the tracks triggered on “high” instead of ground, and I used pin 3 as a “cancel” button. The Bluefruit LE is fun and easy to use. The Flora can parse text packets that come in from the phone app, and trigger actions based on the text packets. I made the Flora activate pins 6 and 12 to turn on my musical tracks, activate pin 10 to cancel the music, and program the Neopixels.
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.
