RGB LED \'OWire\' - 2 Pin PTH 4mm Concave

Have you ever seen those strings of fairy lights, or pre-lit Christmas trees, that change colors with a little remote? Have you ever noticed that they only have two wires? How do they do that? Well it turns out that this is how: Special LEDs!

These 4mm LEDs are like a compromise between color cycling LEDs and fully addressable LEDs. While you aren\'t able to individually address each LED in the chain, you _can_ change the color and mode of _all_ LEDs in the chain. We call these \"OWire\" LEDs because there\'s no \"signal\" wire, just power and ground. In order to change modes you wiggle the power LED in a 7-bit pattern depending on the mode/color you want. Don\'t worry, we\'ve written an Arduino library! A single LED will run just fine from a GPIO pin, but if you want to put a lot of LEDs in parallel, you\'ll want to use a MOSFET to signal the power rail. Check the documents for an example schematic.
