To understand what is happening, we have to delve into the science of light and color. The White Balance setting is based on the color temperature of the light you are shooting in. “Color temperature” is measured on the Kelvin scale, and helps describe the color of light emitted from a hypothetical “black body” as it is being heated. The color of the light will change as the temperature of the black body changes.
Imagine you heat up a chunk of steel, say a horseshoe. Normally a horseshoe doesn’t emit any light (unless you pay extra for the deluxe model). It is the “black body” in our definition above.
But, if you heat it up, it begins to glow. At first we see a dim red, as it grows hotter it becomes more blue. This is color temperature, changes to the temperature of the horseshoe changes the color of light it emits.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
