# Automatic Monitor Color Temperature Adjustment ## Overview https://www.youtube.com/watch?v=yWbRG5oXVYE Staring at a computer monitor all day is quite stressful. Moving your gaze from the cold, white light of a monitor to warmer indoor light is especially jarring to your senses. Programs like [f.lux](http://justgetflux.com/) and [Redshift](http://jonls.dk/redshift/) were created to ease this strain by adjusting the [color temperature](http://en.wikipedia.org/wiki/Color_temperature) of your monitor. However these programs don't measure color temperature of light in the environment and instead guess the temperature based on location, time of day, and sunrise/sunset time. This project will show you how to build hardware that measures the temperature of ambient light and automatically adjusts your monitor color to match. With just a simple RGB color sensor and an Arduino or FT232H-based cable, your computer can easily sense and react to light in its environment. Before building this project, it will be helpful to familiarize yourself with the [color sensor guide](http://learn.adafruit.com/adafruit-color-sensors/overview). - [Next Page](https://learn.adafruit.com/automatic-monitor-color-temperature-adjustment/hardware.md) ## Featured Products ### RGB Color Sensor with IR filter and White LED - TCS34725 [RGB Color Sensor with IR filter and White LED - TCS34725](https://www.adafruit.com/product/1334) Discontinued - **you can grab** [**Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor - STEMMA QT / Qwiic**](https://www.adafruit.com/product/3595) ** instead!** Your electronics can now see in dazzling color with this lovely color light...
