What does the servo class do? Isn't is just a simple PWM signal? It is a PWM signal that is sent at a 50hz instead of 490hz of a standard PWM signal I'm using the code servo.writeMicroseconds with a value of between 1000 and 2000 now instead of just .write (value in degrees) as its easier to unders...

So the code works to output the correct signal from the low ato port Running into another problem in that I need to run through my loop as close as possible to every 20ms for this to work which is not happening. otherwise all I get is random jitters from the motor code examples I have found have ske...

Got the new speed controller today, worked on figuring out how to use servo.write all day hopefully all will work out tomorrow :) here is the code I am going to try out it compiled if anyone who knows better sees a problem with this let me know First you need the servo libraries added to the ReefAng...

I will just get the 6000 from amazon, easy return if it doesn't work out and no duties or brokerage charges. Last time I got a $25 car part from the UK UPS charged me $130 in brokerage charges for the inconvenience of prepaying $2.50 in duty charges. I will order the stuff this week and see how it ...

Is your 35 ppt fluid actually 35 ppt?

Has anyone seen a DCT4000 from a US seller? I can only seem to find it in the UK at a cost of $160 bucks. The DCT6000 is on amazon for 100.

How sure are you that this will work? I'm only asking because I don't want to throw anymore money at something that might work. What kind of programming is involved for the RA? without having done it myself I cannot say for sure it will work, in principle it will. If you don't want to throw more mo...

Since it doesn't sound like this is possible, what would I put into my code to shut the return off if it gets too high? I would use the water level sensor to decide what the max height is and if it gets that high it will shut off port 1. I'm using a gate valve on the drain to create a full siphon s...

Is there any writing at all on the U3 Chip on that board?

Do you mind sending a pic to me of the board? jegillis@yahoo.com


It needs to have an ESC in it just the same, It should have a micro controller in it and some way to tell that controller what you want it to do.

Can't say for sure it would work without documentation for the motor or esc but the specs are ok. the ESC would need to be programmed so make sure that the ESC has appropriate documentation on programming. Roberto can we get a PWM port (ato port/ports) to do PMM? or would a servo shield need to be m...

Alright you could use a programmable ESC like this one http://www.hobbyking.com/hobbyking/store/__24889__Turnigy_Super_Brain_45A_6s_Brushless_ESC.html?gclid=CjwKEAiA9qCnBRCb7ZDhvaHSyicSJABGFFHt45i47A5M189f4B8UokPiPa0b2VxKMHSc5eJuJ5nZFRoCXUjw_wcB You would control the ESC like a servo from the reef a...

I haven't seen this pump but I am gathering that the controller sends 24v PWM to the DC motor to control speed why not just use an appropriately powered LED driver directly to the motor to control the speed? Looks like a Meanwell ELN-60-27P could do it. *EDIT oops this is a three phase motor, needs ...

If you don't have a relay expansion you do not need them

Did the Wizard put those lines in? I just ran the wizard and did not get them.

You can also set a delay on ports turning on after feeding or water change
This is placed in the loop. (port,timeinminutes)


I use it to delay starting my in sump skimmer

I use that container for my top off water, do not expect the top lid to be watertight mine was not...

Ok well the dimmer does not dim anymore everything is just at 100 percent or off nothing in between for all 3 channels

Im getting an overheat problem with the LED driver, channel 0 was shutting off for a few seconds about every 10 seconds. I unplugged the driver and checked the temp inside the case and found it at 150 degrees. I took the cover off and let it cool. Plugged it back in and it appears to be ok for now e...

A 40 ft run with 24 gauge wire (cat 5) on the dimming ports amounts to a 0.1 volt drop assuming if I remember correctly .05 amps from the dimming ports.

It's working!!

video to follow after I get my youtube app to listen to me

Ok if I change the trigger to be sent on channel 2 only channel 2 flashes

No change on the effect still not ramping up.

and it still only flashes channel one

still just channel 1 and with a flash off instead of ramping up

with the dev libraries? Im getting a compiling error with the original

In the latest receiver code posted you used a variable for the channels here for (int n=1; n<3; n++) { int newdata=4095; Wire.beginTransmission(0x40); // Address of the dimming expansion module Wire.write(0x8+(4*n)); // 0x8 is channel 0, 0x12 is channel 1, etc. I'm using channel 1. Wire.write(newdat...

Ok, went back to the other library for now. Just noticed something that may be of help. Where you would expect the lighting to ramp up the whites it is actually flashing off then back on to the level called for in the cloud. At no point during any flash does the light ramp up, like it is working in ...

the new library had another effect, after the storm was over channel 0 and channel 2 shut off completely.
