|The Theme You Picked: Cool LED Display|
|Infrared thermometer||Cotton LED star with Digispark module|
This month's theme is Cool LED Display and comes from dougw. Anything goes with this, you can use LEDs individually to create a display or come up with a creative way to utilize an existing LED display. An LED display build makes a great weekend project. For example, you can take a cheap microcontroller such as an Arduino, some LED pixels, some everyday items, and something you picked up from Ikea for your project. Or you can make a monochrome display, something with holiday spirit, an LED Cube, make an LED calculator, or do your own special lighting effects.
The only LEDs that were around for the first 10 years they were around were red visible light. Ten years later there was Green LED. In 1994, there was blue LED. You can get blue or green LED through a mixture of Gallium Nitride and Indium Nitride to get the blue, called Indium Gallium Nitride (INGaN).
Varying the amount of Indium in the mix varies the color of blue. Red, orange, and yellow LEDs use variants of Gallium Phosphide (GaP) Gallium Arsenide Phosphide (GaAsP) to get their hues. With white LEDs a blue or violet LED is coated with a phosphor that emits photons from the ultraviolet frequencies when the LED is energized.
