New Jarduino build gets started

[reefme]

Is anyone have LDD-350H drivers spare? Would be nice if I could have three.

Thanks,
Kevin

Fairly confident it's:

Blk - grnd
Red - +
Yellow - Tach
Blue - PWM

I've had a number of fans with a similar set up.

I have spare 700's and 1000's, that's it.


Scubasteve: Sweet, thanks!

Ya, I have the same things (700 & 1000).

Well again another very early morning thanks to the ever so diligent crows and robins
Oh, well, might as well do something constructive. This is what my office now looks like, lol



And I got everything hooked up and it seems to be running, yaaaaaaay



The Arduino up and running the code:



And a shot of the panel box everything is mounted in temporarily:




I'm still waiting for my amphenol connectors that's why everything is only temporarily connected. I couldn't think of another way to test fire everything at once to make sure it all worked together. I also want to get this thing over my 77 gal and see if it has a positive effect on the coral and algae I just can't seem to kick. I do have MH bulbs that are 8 months old or so and at this point I'm not buying bulbs with this thing so close to operational.
I also have not finished my fan circuitry so right now the fans are not running on my heatsinks so that's next on the priority list.
I also have to fine tune the Arduino code because I have a couple channels used that the original code was using for sump lights and such that I'm not using. So I have to figure that out.

Anyway, that's an update for now. Hope ya'll enjoy. It appears to be getting lots of views but it's so quite in here

Got a question for all you wiring guru's. I want all my components housed by my arduino, I really don't want anything sitting on a heatsink. For ease of replacement/service, I also didn't want to link the LED's to each other. I want to be able to remove a fixture and not have it affect the other 2. So I have thus far gone to fairly great lengths in planning to accomplish that. BUT, turns out I'm 1 wire short to my fixtures, DU'OH!!!!!!
I have 8 strings of lights = 16 wires. My fan requires 3 wires for power and PWM and the heat sensor for the heatsinks require 3 wires. For a total of 22 needed wires. But the wire I have only has 21
Is there any way I can share a wire in the fan/sensor circuitry? Or am I going to have to run 1 single wire for my sensor or fan?

[ScubaSteve]

What kind of heat sensor are you using? I imagine that the sensor and the fan could share a common ground.

[daplatapus]

I'm was going to be using the DS18B20. It's got 3 legs on it 1 of which is a ground that goes to the Arduino's ground plane. I though maybe I could share that ground too but by Chris' schematic the fan grounds all go through either a 10K resistor or through a 2N3904 transistor and I wasn't sure if that would work...

Which actually brought me to another question about that 10K resistor. All I have here is a huge 3W10K resistor, will that still work in that fan circuit?

tagging along, this is really cool

OOOOoooohhhh, look what I got today
