Have fun with uLisp on the Circuit Playground Bluefruit


If you want an interesting platform to experiment with controlling a range of sensors from uLisp then Adafruit’s Circuit Playground Bluefruit might be just what you’re looking for:

It’s based on the Nordic Semiconductor nRF52840 ARM Cortex-M4 microcontroller running at 64 MHz, with 1 Mbyte of flash program memory and 256 Kbytes of RAM. It includes a range of sensors and other peripherals, including:

  • Ten mini RGB NeoPixels.
  • An LIS3DH triple-axis accelerometer.
  • A temperature sensor (thermistor).
  • A light sensor (phototransistor).
  • A sound sensor (MEMS microphone).
  • A mini speaker with a class D amplifier.
  • Two push buttons, labelled A and B.
  • A slide switch.
  • Eight alligator-clip friendly input/output pins.
  • A green power LED, and a red LED on :led-builtin .
  • A reset button.

For details of installing uLisp on the board, and examples of how to access the NeoPixels, sensors, and other peripherals from uLisp, see:
