Color LEDs 4 mm, which is a solution between "ordinary" LEDs and fully addressable LEDs. The user cannot address each diode in the chain, but can change the color and mode of all the diodes in the chain. "OWire" has no signal wire, only power and ground. To change the mode, change the state of the power LED in a 7-bit pattern depending on the mode/color you want. A single LED can be controlled via a GPIO pin, but if you want to put multiple LEDs in parallel, use a MOSFET for power signaling. Sample wiring diagrams and full documentation are available on the product page.
