Documentation

Python LED Strip Bluetooth Controller API was created by Douglas Paz implemented with bleak.

Supported controllers/devices

MELK: MELKController

Install

Install from Pypi repository.

pip install btledstrip

Usage

from btledstrip import (
    BTLedStrip,
    MELKController,
)

mac_address = "00:00:00:00:00:00"
controller = MELKController()
async with BTLedStrip(controller, mac_address) as led_strip:
    # turn on
    await led_strip.exec.turn_on()
    # turn off
    await led_strip.exec.turn_off()

Demonstrations

MELK:
