Chinese made LED diy
Was thinking the AD5282 would work fine. i2c is pretty easy: gnd, 5v, sda, scl come from the RA i2c bus. Stiffening cap on AD5282 vcc line. Hook up the dim+ and dim- on the drivers to the appropriate resistor and wiper terminals. Then just find or write a new arduino class to control the AD5282.

Wow, sounds like a great solution.

How would you control multiple fixtures? I'm guessing you'd need a few of those and give each one their own address? Ir would you be able to wire multiple pots to each channel?

Im still liking them they work great . Everything in my tank is growing like crazy. Im still wanting to add a actinic strip of royal blues to the system eventually. I also thought about adding a red or two as well. I havent been able to do much research on the red leds yet and if I truly would need them. Sent from my SAMSUNG-SGH-I337 using Tapatalk |

Thanks I was thinking of adding 1 4' strip from Buildmyled.com of their 14000K lighting.
You just have the Meanwell drivers connected to the lights and you are getting dimming control, correct? I keep see these post from KRavEN that looks like he is doing something much more elaborate. |

Yup mines just wired in right between the wall outlet and 5he fixture. I just removed the old one power supplies and wired the meanwells in. I would take a picture but its a mess and I haven't had a chance to clean it up. The drivers dont dim all the way to 0 only to about 15 before the fixture cuts off. I tend to only run my whites up to 60% throughout the day and the blues are at 100 %

Cool. thanks for the info. I'm still leaning towards this setup, just need to get the money together.
Every time I'm able to save some money something "important" comes up and I have to pay a stupid bill or get food for the family. Jeeze they don't really need to eat 3 times a day every day do they??? |

That chip is a dual channel chip. The way my light is wired is I have 3 drivers on one pot and 3 drivers on the other. I could go with 3 of these chips and control all 6 individually but the way the led layout I don't think it's worth it. I'll just replace the 2 manual pots with the dual digital pot. Yes, multiple fixtures multiple chips with different addresses. The address is set via pins on the chip being pulled high or low. |

So this would work to replace any manual dimmer then?
|
|
Should. I still need to get one and try it out.
