part 2: set theme according to surrounding light

you can use the following, to use a the webcam to sense the surrounding light as a trigger:

#!/bin/bash

# Capture an image
ffmpeg -y -f video4linux2 -i /dev/video0 -frames 1 snapshot.jpg > /dev/null 2>&1

# Calculate brightness
brightness=$(convert snapshot.jpg -colorspace Gray -format "%[fx:mean]" info:)

# Define threshold
threshold=0.5  # Adjust this based on your preference

# Check brightness and set theme
if (( $(echo "$brightness > $threshold" | bc -l) )); then
    echo "L I G H T"
    # Command to set light theme
else
    echo "D A R K"
    # Command to set dark theme
fi
