Hey everyone, I'm in need of some information ranging from extremely general to pretty specific. So here it goes. I am building a canopy for my aquarium using Cree XP LEDs. I have a 24V, 6.5A Potrans power supply running two 1000mA Wired Buckpucks W/ Pots, which each drive a string of 6 XP-G's and XP-E's mounted on star boards. Here is a schematic of my circuit. See next Post. I have included links to all of my components below for reference information.
So I'm thinking I can hook up the 0-5v line on the driver to a PWM port on an arduino, I just don't know what to do with the other one? I also want to have these all reference a real time value, so I can independently have each string fade in at out at certain time intervals.
My first string of questions being: 1| Where would the Arduino fit in all this? Can I run it off the 24V supply? 2| How can I attach the Pucks to the Arduino for control? 3| Im interested in possibly adding one more string for moonlights, that in mind, which Arduino would be best for me? 4| Is there a real time chip or shield that I would need to get?
I'm doing my share of reading, i'm not the best with electrical stuff, so its requiring quite a learning curve before a lot of even the basic reading makes full sense.
Thanks in advance! Brian
