Goal Horn Program

This program monitors your screen for a specific image (representing a "goal") and, when detected, triggers a connected LIFX smart bulb to change color and play a goal horn sound.

What the Code Does

1. LIFX Integration:
   The code uses the lifxlan library to communicate with a LIFX smart bulb. It discovers the bulb (based on MAC address and IP), turns it on, and changes its color.

2. Screen Detection:
   Using pyautogui, the script continuously scans a specific region of the screen for a reference image (goal.jpg). When it detects the goal image, it proceeds to the "goal event" sequence.

3. Goal Event Sequence:

   • Light Color Change: The bulb’s color changes to red (or another specified color).
   • Play Horn Sound: With pygame, it plays an MP3 horn sound (dontStopTheParty.mp3).
   • Revert Color: After a 20-second delay, the bulb’s color reverts to its original state.

Requirements

• Python 3.7+ (Recommended)
• Virtual Environment (Optional) to isolate dependencies.

Installing Dependencies

A requirements.txt file is included. It lists all the required Python packages:

• lifxlan
• python-dotenv
• pyautogui
• pygame

---

Steps to Set Up:

1. Check Python and pip:

   python --version
   pip --version
   

2. Create and Activate a Virtual Environment (Recommended):

   `python -m venv venv`
   # On Linux/MacOS
   `source venv/bin/activate`
   # On Windows
   `venv\Scripts\activate`
   

3. Install all required packages: pip install -r requirements.txt

Setting Up Environment Variables

The code uses environment variables for the LIFX bulb’s MAC address and IP. The .env file should parameters shown in the .env.example file

• Create a .env file in the project root if it doesn’t exist.
• Copy the contents of the .env.example file and replace the required values.

What Happens:

1. The script attempts to connect to the LIFX bulb and turn it on.
2. It starts scanning the specified region of the screen for `goal.jpg`.
3. When the goal image is detected:
- It prints "Goal found!"
- Changes the light color to red
- Plays the horn sound
- Waits 20 seconds
- Reverts the light to its original color
