Okay this is probably exactly what I did wrong. I didn't know this chip went in a certain direction, I should have known.

Had to run to work but as soon as I get back I'm going to check this thank you so much everyone

This was it! Thanks again for the help. Going to start a build thread per Ranjib

Just wondering if the dosing pump section ever got setup to use nema 17 motors? Im looking at this to run my planted tank/ not a reef tank. but a friend is wanting to set up a hydroponic greenhouse garden. I remembered looking at this like a year ago and thinking it was a good idea, but new to electronics. now I feel comfortable doing this to my tank. I just remembered this cause he was wanting to automate his garden and this came to mind. control lights\fans, and dosing fertlizers.

So I am trying to do some work on MACROS and ATOs my problem is that I would like to have an ATO shut my main pump off if for whatever reason my overflows get plugged and go to and the issue is that if i run a feed MACRO the ATO kick the pump back on when the ATO times out that is still low. I know I could add another relay to work in series with my pump so both would have to be on to make. But is there any other way around this. maybe add an option to set macros as a master to control relays and ATO as a secondary if not running a macro.
Thanks for the help

Macro's just run a set of command in a row until finished. For example - stop equipment A, wait 15 seconds, then start equipment A. After it's done that, the macro goes back to a waiting state to be run again. Macro's aren't for collecting a bunch of settings.

For what you are describing, you want to set up a dedicated ATO with associated float switch/ optical switch. That running as a module to control the pump will work.

Ok, my dashboard bug has gone away after I changed my equipment names, is there a limit on the naming of the equipment?, I had 8 outlets named as blue1, blue2 and so on up to 4, then white1 up to 4 again to make 8, once I changed them to 1,2,3,4,5,6,7,8 all is good again and it displays under each bar of the dashboard for the equipment now, it didn't really do that how I set it up at first.

The software and basic electronics (that generate 2 to 16 channel pwm signal ) will remain same, but you'll need NEMA17 stepper motor compatible driver (like DRV8833) and additional power for them.

So it is good now? I am not able to understand it fully, the equipment chart is now showing the labels(equipment name)? The charting library may decide to not show labels if its space constrained.

Yes the bug has gone, I also cleared my browser cache, it would show under equipment blue4 and white4, I thought it was a feature but the wording was off to the right, another thing I noticed if i put phone in landscape it would then show blue3 whit4 for the labels

Correct I did do the floats but I also want a feed macro to shut the pump off to feed them delay 10 min and come back on however after the ato 2 min check timer runs out the pump comes back on so I dont get a 10 min feed mode. I'm guessing I'll have to have my pump run through two relays one ran by the ato and one ran by a macro. Maybe in a future release you could made it so if something is running in s macro it would ignore the ato. Also maybe an ato override button. I gave a mixing setup and the way it's set the mix pump and heater will shutoff when the tank is empty however I also use that pump to transfer water from my ro tank to my mixing tank. But if its empty the ato for low mixing tank shuts it off.
Thanks for the help

My feed macro runs like this :-

Disable ATO
Disable Temperature control
Turn off Return Pump
Turn off wavemaker
Wait 15 minutes
Turn on wavemaker
Wait 45 minutes
Turn on Return Pump
Enable ATO
Enable Temperature Control

That works for me.

Awesome I didn't realize you could disable ATO thanks for the help and fast response. Guess I should have done some more tinkering before I asked. Thanks again

I was gonna use a breakoutboard with 8825 drivers with a 12v powersupply. I am used to using nema 17 motors with cnc and 3d printing, but never used one with a raspberry pi before, so not sure how to wire/control it. But I'm sure I can figure it out.

@Mwdsonny -
If and when you do figure it out, please let us know how it works and what pump housing you used with the NEMA pump. It's my understanding the NEMA pumps are very accurate.
Better yet, it would be great if you started your own build thread with list of materials, directions for wiring, etc!

I am an electrician by trade, but the control/calibrate part I need help with, once I get it working Ill do a writeup and wiring setup for yall. just want to make sure it works correctly with the software. Im currently using my pi to control my 3d printer. but the printer has its own control board, just using the pi as a iot connection instead of connecting it directly to my laptop. Waiting on my 2nd pi 3 (this one will be a 3+ where current is original 3). and ordered a 8 relay station thats 3.3 volt turnon to run directly off gpio pins. to make it easy.

This should work fine. Last time I checked, it was suggested to go for less than 20ma current draw from GPIO and over all current draw from Pi should be less than 800 (including the 5V / 3.3V pin). SainSmart relay board manual has an example circuit. I have never encountered this, and most of my 1.0 build ran straight from GPIO, post 1.4 I was using ULN2803. And now I am exclusively on ADJ power strips. If anything I would be curious how long they can run (I took mine off after 1 year 2-3 months, but it was still in working condition)

yes :-) , isn’t that nice

I need a little assistance. I have a budget to work with and need to find an accurate shopping list. I was wondering if the one in the very first few posts to this forum is accurate and if there would be anything else I would need.

I think the first question is what do you want it to be capable of doing?

Shop around, eBay, Amazon, online electronics shops, and if you can wait for postage most stuff is very cheap from china
