I'm putting together a design for an aquarium fixture that will be using buckpucks to drive strings of LED's. I want to use the dimable buckpucks, but they're designed to be dimmed with a pot.
My question is, can I use the PWM output on the Arduino to drive the control pin on the buckpuck safely? I'm going to be hooking up 12 buckpucks and 72 1 amp LED's to this, so I really need to get it right.
I think the answer is yes, but I could really use some expert opinions. In particular, about how to do it "right", as I'll have almost a thousand dollars in parts in this build.
