Hi,

I'm looking for a way to control specifically these rgb LED's:

https://www.amazon.com/SUPERNIGHT-Waterproof-300LEDs-Changing-Flexible/dp/B00DTOAWZ2/ref=sr_1_1?ie=UTF8&qid=1511076833&sr=8-1&keywords=rgb+lights

They have 4 pins- red, green, blue, and 1 for (control?). Is there a way to control the lighting levels from an Arduino? I don't know what to plug into the board, and how I would control the amount of power going to each pin. I've looked up I have years of coding, so creating an algorithm to control it all isn't an issue.

Thanks,
Eric

The four wires on a typical RGB strip are common anode or cathode (5V or ground) and analog/current-limited/PWM power/ground on the RGB lines to manage intensity.

On a typical Arduino/Atmel, you would use three PWM channels to drive the RGB outputs using an adequate current-limiting resistor and boost transistor to handle the current.
