DIY automatic kh tester

axlzys · Sep 22, 2021

hello guys
i made a automatic kh tester with Arduino,
and the case made by 3d printer，
two dc motor and one step motor,

but i have a problem,
i was learned c++ ten years ago, just little.
now i don’t know how to save the date in a html,
the tester only can display last one result in oled.

If you open source the project you might get lucky and find a couple of people willing to help you with the missing bits...

the code is very crude .a lot of delay() in the code.

I put together a titrator using Raspberry Pi
I have been using it for four years.
I am constantly redoing something.
Accuracy 0.1 kh compared to Hanna.

Good luck with your project!

Looks awesome! Are you planning to publish it so others can replicate, by any chance?

I presume you use one of the RTC chips to keep track of time? Arduino's don't have a built-in clock, just a timer allowing to count milliseconds (up to 11 days).

Awesome... do you have plans on how to build this? Interested...

Nice! Almost as good as mine!

The project is moving slowly ...

I want to build one to, but I don’t really have any knowledge on how to use Arduino or anything like that is there anyway anyone can help me?

Help you with what exactly?

Like is there a walkthrough on what pieces I need and what programs I need?

Sure, most of these projects are controlled by Arduino, a comprehensive guide on getting started can be found here:

Tutorials | Arduino Documentation

Arduino featured tutorials

www.arduino.cc

The programming part is actually the easiest one, connecting pump motors, PH board and stirrer is a bit more complicated. Generally such project is not for beginners and I would recommend to start with a simpller one..

In terms of wiring - the schematic diagaram for a peristaltic pump can be found here:

I don’t know any actual programming language, but do know a bit about them in general…would using Python language work? My understanding is that Python is fairly easy for folks to learn / use…

Aruino runs on C++.. however most use of C++ is very basic. If you programmed in other languages you shoulld be able to adapt to write simple Arduino programs.. But generally no to Python (and BTW it's a horrible language with almost no structure)..

Sure, check out the pyduino. Or you could use a raspberry pi, they are python native.

Is this an open source project with STL to print uploaded somewhere ? I'm very interested...
