BLE service for Magic Light BLE RGB bulbs. Available from Amazon [here](https://www.amazon.com/gp/product/B073S1KV4F).
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Note
This library is not available on PyPI yet. Install documentation is included as a standard element. Stay tuned f 8A47 or PyPI availability!
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-ble-magic-lightTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-ble-magic-lightTo install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-ble-magic-light"""This demo connects to a magic light and has it do a color wheel."""
