Starting with version 10.3.0-alpha.3 CircuitPython has added a new audioi2sin module on Raspberry Pi and Espressif based devices. The new module unlocks the ability for I2S microphones like the ICS43434 or SPH0645LM4H to be used in CircuitPython projects. This guide will demonstrate the new capabilities with 3 examples: A basic script to record audio to a […]

User danak on the Adafruit Learning System Playground has written a Note entitled &#8220;Getting my Fruit Jam Clock to Speak&#8221;. The (Adafruit) Fruit Jam, with its built‑in audio, WiFi, HSTX display, SD card, generous memory, and other little goodies, is a fantastic platform for mixing creativity with a bit of technical magic. Add CircuitPython to [&#8230;]

We got two more #CircuitPython2026 over the weekend and tomorrow is the last day to get them in. So, please post ASAP and email circuitpython2026@adafruit.com too. Thanks! Tim (aka FoamyGuy) posted a GitHub gist about working on MIDI and RAG (Retrieval augmented generation) based AI tools for CircuitPython. jgmangum posted to the forum a request [&#8230;]

Campus School’s collaboration with Professor John Gallaugher’s Physical Computing class was once again a success last semester. After an initial visit led by Assistive Technology Professional Meghan, students learned how adaptive and assistive technology can remove barriers, promote independence, and bring joy to learning. Undergraduate and graduate students designed and built customized projects to support Campus School students, including:•Motivational Words of the Day Sign: Accessible switch-activated encouragement by undergrads Gonzalo Verdugo and Michael Donohue•Tail for Baby Lizard Companion: Multi-sensory tactile, sound, and light experience by graduate student Shamili Satheesan•Adapted Tic Tac Toe: Accessible two-player game using capacitive touch by Esha Patel, graduate student, and Jennifer Weber, undergrad exchange student from Germany•Laser Harp: Music created through hand movement with visual and auditory feedback by undergrads Daniel Martin and Jack Tommaney•Adapted Soccer Goal: A switch-accessible activity with celebratory visuals by undergrads Meghan Schouten and Michelle Kang🎥 Learn more via the video link in bio—Campus School projects appear at 2:45.#CampusSchoolatBC #BCEagles #WeAreBC #specialeducation #BCAlumni @john.gallaugher @bcalumni @bclynchschool @bostoncollege @bccarrollschool IDs:1.

About the Pixel Kit The retail Pixel Kit uses an ESP32 (The classic one) (ESP-WROOM-32) with 4MB of flash, which makes it very easy to put things like WLED, Arduino, MicroPython, and CircuitPython onto it. Flashing CircuitPython onto Your Pixel Kit To flash CircuitPython onto it, either use Thonny (A python editor for basically anything) or esptool (A Python-based CLI tool for ESP32) Thonny: Click Tools (in bar on top) Select "Options..." Select "Interpreter" Click the dropdown and select CircuitPython (generic) Click the underlined text "esptool", this tells Thonny to flash to ESP32 Select the COM (Windows) or dev/cu.usbmodem (Mac) (Could also be dev/tty.usbserial) port in the Target Port dropdown For family select ESP32 (This is what the Pixel Kit has) For variant select DOIT • ESP32 Development Board Select what CircuitPython version you want in the version dropdown Click Install Close the installer window Select the port for your device Click the stop button (Stop/Restart Backend) Install the necessary libraries from the bundle in their documentation. neopixel, adafruit_framebuf, adafruit_pixel_framebuf, and led_animation Download the CircuitPython PixelKit library from my GitHub repo (PixelKit.py) https://github.com/colinvail6/pixelkit-lib Install it to /lib Play around with the Pixel Kit! esptool: Install esptool. This can be done using pip install esptool (Python 2 and lower) or pip3 install esptool (Python 3 and newer) Open your Terminal app (Terminal on Mac, Command Prompt on Windows, Bash on Linux) Erase the flash on your board. This can be done using esptool --port %PORT% --chip esp32 erase_flash (Python 2 or lower) or python -m esptool --port %PORT% --chip esp32 erase_flash (Python 3 and newer) Download the CircuitPython binary from https://circuitpython.org/board/doit_esp32_devkit_v1/ Run cd Downloads Flash the CircuitPython binary to your Pixel Kit.

You can build your own interactive, wireless musical LED juggling balls using CircuitPython and the low latency ESP-NOW protocol. Use them to trigger MIDI notes on your computer or hardware synth, and control the RGB NeoPixel LEDs wirelessly. These juggling balls shine bright with NeoPixels, and can wirelessly trigger MIDI notes based on catch detection [&#8230;]
