I know there are a few topics on the subject already but I have quite a few questions and didn't want to hijack the other threads.
I want to be able to control LED strings (something like this). Now I understand that this will be a lot of learning for me and a rather big project, but I'm happy to take that on.
First things first: I have a AC/DC power supply that can supply 6A at 12V no problem. I know how to code C (and C++).
My questions are:
1) Where do I start? Can the RPi do this? Obviously the power that the LEDs require cannot be supplied by the RPi hence the external PSU, but how would I go about connecting it all up? I want the RPi to be able to dim the LEDs from 0% - 100% (I know that the LEDs dimming curve isn't great but I'll live with it).
(I'm thinking that V+ goes to the cathode, while the anodes of the LEDs are connected to the GPIO pins of the RPi, but not sure if I've got the right idea).
2) Is there something I should read that'll give me more clues?
3) Anything else?
