I want to control 10 different 12V RGB LED strips independently from a single Arduino.
As a clarification - I've setup a bunch of NeoPixels and understand how to wire and control them independently. So now I'm looking to do something similar but rather than set color of individual LED's, I'm looking to set color of LED strips.
I've already done all the research to understand how to use a MOSFET to control a single strip - but that requires 3 PWM outputs on the Arduino board and I don't see any boards that have 3 * 10 = 30 PWM outputs.
Are there existing controllers that can abstract the power conversion and voltage control, so I can just send a color and brightness setting from the Arduino to each strip?
