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 and Redshift were created to ease this strain by adjusting the 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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
