Arduino controlled LED Fixture

Ok stand is done! I am waiting on my glass for my sump baffles and then I will be able to drain the tank and move it over to the new stand. I had some arms welded to hold my light fixture and mounted them on the back.

and here I am all proud of setting up my own 58g and doing some simple diy projects for it, this is freakin' sick! way to go!
 
HI Ghellin,
Can you please tell me where you get the CAT1401 pcb from or you have any spare that I can buy. This is exactly what I need for my new build, 39G aqueon bowfront.
Thanks-MiReef

Thank you very much I cant wait to get this up and running! I love the 58 gallon tanks. I am also trying to figure out if I want two MP10's or a single MP40 for flow. Then I need to get a second job to buy them LOL.

MiReef I did get mine TheFishMan in a big group buy. I don't have any spare PCBs just the one. I know if you get them from seedstudio you can easily sell the rest. I know if you post you are in need of some someone will most likely PM you with their extras.
 
Thanks Ghellin,
I actually post in the DIY forum asking both TheFishMan and DWZM. Hope someone will chime in. Thanks
 
This last weekend I was finally able to get the tank moved over to the new stand I am still running t5s for now but hopefully I will finish the fixure soon.

We have light! I finished the wiring and fired the light up i won't be able to play with it much since I am going to Bogota Columbia for a while. But here are a few pics

I have made a little more progress with the controller and display. I added an I2C backpack to free up a few more PWM pins on my arduino. Now i will be able to control 4 separate channels of LEDs 2 temp sensors one for the water temp and one for LED heatsink temp. As well as 2 pins to control relays to for a heater and manage pumps for feeding time.


My new I2C backpack soldered on.

Code up and running temp sensors not installed so the default is 32 degrees.

Greg,
What degree optics are you running? Also, what is the resistor block for? Is that the current-limiting resisor for the circuit?
 
I am running one 0.1 Ohm 1/2 1% watt resistor so I can easily test the current with a multimeter. Currently I am using 40 degree optics but I am going to change to 65 degrees, my fixture ended up being a little lower than I originally planned.
 
Gotcha. So it's not really a needed part of the circuit? Just something you added for ease of "maintenance".
 
Yeah with the cat 4101 driver I am using I can make small current adjustments on each string so this makes it easy to see where to set them.
