Well obviously the Arduino is not gonna power the tanklights all by itself, that's why you use the PWM signal to control the gate on an N-channel MOSFET, I think?
![]()
This example is for 3 channels, but its all the same. Plus ofcourse the power being drawn from an external supply (shared GND!).
I thought you had to use a servo driver board to unpack the PPM-train into individual PWM signals, because the code involves PCA9865. But apparently that's just an option, and the channel PWM signals are available on pins 2 ~7 anyway.

Awc?
Hello everyone,
First, Thanks a lot to all the contributors here!
I am very interested in this project. I would like to build one for my own use. But I have a question:
Has any sort of automatic water change (AWC) system been implemented with iAqua?
If not, can something be done? It could be as simple as using two floats (one bottom, one top) as sensors. At a set time, turn on a pump. Old water goes out. When both floats go low, latch another pump "on" until the top float goes high. Yeah, I know......easier said than done! LoL
PS: I did search this thread but did not find any reference to AWC. ATO functionality is there, I hear.

I agree, I would love to have a system to do an AWC, not just an ATO
https://www.bulkreefsupply.com/awc-auto-water-changer-plus-ato-autoaqua.html
this system would include what I want but it's expensive for a stand alone system
Here's a cheaper alternative...

It's not on their website, but when I emailed that guy (Paul, very nice guy), he sent me a PDF describing a custom controller setup. It's around 150 bucks.

Hmmmm...I wonder if anyone is still using and maintaining code for this project. This thread was started 6 years back. The OP has been absent for 5 years.
There is another project called Mr. Aqua on GitHub, linked in here somewhere. Its notes say that it is based on this code...but even that is 2 years old.
I wonder if I am barking up the wrong tree.
Should I look for something more modern and actively developed and supported?
Any tips, anyone?
Bueller? ;-)

Some of us have started projects using the RaspberryPi4 and NodeRed. Albiet, we rely heavily on sensors/circuits over i2c from Atlas-Scientific for measurement and dosing. Likewise, I'm using i/o boards from NCD.io for Control (relays / pwm).
Here's a good link to MaddyP's work on reef2reef (salwater focus): https://www.reef2reef.com/threads/w...ode-red-raspberry-pi-controller-build.716452/
My thread is here on NodeRed, however, I have to get them to re-open it so I can post my latest modifications: https://discourse.nodered.org/t/aqu...entific-i2c-devices-ncd-i2c-relay-board/25839
Maddy's work is more interesting becuase he's doing allot of custom html for UI...
Thanks for chiming in here.
I took a peek at your work a few months back, at that time it seemed (to me) a little more than I could chew.
Do you have a working prototype now?
I'll check out Maddy's work. Thanks for that pointer.
iAqua seemed to me that it was a complete, working thing. There are some videos on YouTube for it, people doing a quick demo. Seems quite old now. I guess those parts (which he used) are no longer available easily.

I can share a working code, that went through some modifications. Works great still after 5-6 years (?) Best time spend on building something for my tanks. If you have the knowledge, then go ahead with iAqua. Not sure what support for the code you mean. It is a simple code, based on Arduino, so no operating system behind or anything like that.
These days, people are doing reef-pi, which is a different concept, requiring different type of knowledge. I am finishing my built on of reef-pi adapted to planted tanks, hopefully to be able to post the built soon (1-2 months). It is an option, and i tried just out of curiosity. Maybe with more potential, and actively maintained, but on the other, hand, it is a more complex solution. To change something requires much more programing skills. It is also more expensive solution. However, to get simple things to work is somehow also easier.
bottom line, either one will work fine, and if I would be at the beginning of choosing, I am still not sure which one is better - both a great!

the original is on GitHub, see the first page. In case you want a slightly modified version, with 3 dosing pump and more On/Off periods here is my code

Hi friend I have been using this controller for more than 4 years successfully and I thought it would be great if you could control the addition of co2 more precisely using a ph electrode.Do you have any options to control the ph?
All my respect for the work done.

Hello guys, I apologize for my bad English because I am writing with translation. I did the MrAqua installation but the screen is reversed, there is no problem in the touch part, but I tried all the drivers but the same problem. Has anyone had this problem before who can help.
![1026761]()
When I install the CTE32_R2 driver, the screen returns to normal but this time the touchscreen is not working.
