The als-led-backlight project enables the automatic control of keyboard and LCD backlights through an Ambient Light Sensor on Linux systems. By utilizing input from the sensor, this program dynamically adjusts the brightness of the keyboard backlight based on the surrounding light conditions, enhancing usability and energy efficiency.

Key Features

• Automatic Adjustment: The tool automatically modulates backlight intensity in real-time, providing an optimal experience based on ambient light levels.
• Future Integration: Plans are underway to expand functionality to include LCD backlight control, offering comprehensive lighting management.

System Requirements

• Operating System: Linux
• Required Tools: gcc and make

Usage Example

To run the application, simply execute the following command:

# ./build/als-led-backlight

Configuration

The application allows configuration through a dedicated file located at /etc/als-led-backlight.conf, where users can set a base reading threshold, tailoring the sensitivity of the ambient light response.

By optimizing the backlight functionality, this project not only boosts user experience but also contributes to better energy management in portable devices.
