BlueLights 0.2

A library for controlling MohuanLED lights via Bluetooth

🌈 MohuanLED Bluetooth Control

BJ_LED_M is a Python library designed to control MohuanLED brand lights via Bluetooth, directly from your laptop or PC (you’ll need a Bluetooth adapter if it’s not built-in). This library allows you to perform simple actions like turning the lights on/off, changing colors, and applying animations or reactions to external events. It also includes a PyQt6-based GUI for more intuitive control over the lights. 🌟

🚀 Usage

The library is fully asynchronous, so you'll need to use asyncio and await. Here's an example of how to establish a direct connection, knowing the UUID and MAC address of the LEDs:

from bj_led import BJLEDInstance
import asyncio

ADDRESS = '64:11:a8:00:8b:a6'                      # Example address
UUID = '0000ee02-0000-1000-2000-00805f9b34fb'      # Example UUID

async def main():
    led = BJLEDInstance(address=ADDRESS, uuid=UUID)

    await led.turn_on()
    await led.set_color_to_rgb(255, 0, 0)          # Change color to red (RGB)

    await asyncio.sleep(5)                         # Wait 5 seconds
    await led.turn_off()                           # Turn off LEDs and disconnect
    await led._disconnect()                        # Clear the buffer
     
asyncio.run(main())

A dynamic example with the same orders:

from bj_led import BJLEDInstance
import asyncio

async def main():
    led = BJLEDInstance()                          # The Scanner will look for 'BJ_LED_M' (name of the devices) and connect

    await led.turn_on()
    await led.set_color_to_rgb(255, 0, 0)          # Change color to red (RGB)

    await asyncio.sleep(5)                         # Wait 5 seconds
    await led.turn_off()                           # Turn off LEDs and disconnect
    await led._disconnect()                        # Clear the buffer
     
asyncio.run(main())

⚙️ Features

• Control MohuanLED lights via Bluetooth (BLE)
• Turn the LEDs on and off 💡
• Change colors across the full RGB spectrum 🎨
• Apply effects like:
  • 🔄 Color fade
  • 💡 Color strobe
  • 🌬️ Breathing effect between colors
  • 🌈 Rainbow cycle
  • 🌊 Wave effect
• Graphical user interface (GUI) using PyQt6 (In development 🛠️)
• Command Line Interface (CLI) for basic commands (In development 🛠️)
• Dynamic MohuanLED device scanner for easy connections (In development 🛠️)
• Automatic detection of UUIDs and MAC addresses

🛠️ Installation

Requirements

• Python 3.8 or higher
• PyQt6 and qasync
• Built-in or external Bluetooth adapter
• MohuanLED lights

You can install the library via pip:

pip install BJ_LED_M

Or install it directly from the repository:

git clone https://github.com/Walkercito/MohuanLED-Bluetooth_LED
cd BJ_LED_M
pip install .

🌈 Applying Effects

You can add various effects to the lights, such as rainbow_cycle, wave_effect, or strobe_light. Here are a few examples:

# Apply the 'rainbow_cycle' effect
await led.rainbow_cycle(duration_per_color=5.0)

# Apply the 'strobe_light' effect with 10 flashes
await led.strobe_light(color=(255, 255, 255), duration=5.0, flashes=10)

🖥️ GUI Control

The library also provides a graphical user interface (GUI) built with PyQt6 to visually control the lights.

To launch the GUI:

python -m bj_led.gui.app

The GUI includes sliders to adjust RGB values and buttons to control the lights and apply effects like fading and color cycling.

⚙️ Configuration

You can configure your setup using an .env file to store your MohuanLED light’s MAC address and UUID.

Create a .env file in the project directory with the following structure:

LED_MAC_ADDRESS=xx:xx:xx:xx:xx:xx
LED_UUID=0000xxxx-0000-1000-8000-00805f9b34fb

The library will automatically load these values when you instantiate the LEDs.

🛠️ Development

If you want to contribute or modify the project, you can set up the development environment as follows:

Clone the repository:

git clone https://github.com/Walkercito/MohuanLED-Bluetooth_LED

Install the dependencies:

pip install -r requirements.txt
