Adafruit Services for CircuitPython: Use BLE to Talk to Sensors, NeoPixels, and More #ble #circuitpython @adafruit @circuitpython

Bluefruit Playground appBluefruit Web Bluetooth Dashboard

There’s a new Bluetooth BLE library for CircuitPython, adafruit_ble_adafruit, which defines a bunch of Adafruit BLE Services for talking to sensors, controlling NeoPixels and DotStars, and playing tones.

We already have an Arduino BLE library for these services, which you can use with the Bluefruit Playground phone/tablet app, the Bluefruit Web Bluetooth Dashboard, or your own client program. Now you can use CircuitPython too! Check out those links for details. We’ll be adding more Guides to show you how to read and report data using these services.

Here’s the current list of services, so you can get an idea of what’s available:

  • Addressable Pixel Service (NeoPixels and DotStars)
  • Barometric Pressure Service
  • Button Service (on-board buttons and switches)
  • Color Sensor Service
  • Gesture Service (for gesture sensors like the APDS9960, which is on the CLUE and Bluefruit Feather Sense boards)
  • Gyroscope Service
  • Humidity Service
  • Light Sensor Service
  • Magnetometer Service
  • Microphone Service
  • Proximity Service (e.g., APDS9960 again)
  • Quaternion Service
  • Temperature Service
  • Tone Service (play tones)


Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here:

Adafruit is on Mastodon, join in!

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, 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.
