Arduino PH tester

So I’m trying to build a PH tester…

After looking through reviews, i believe using an Arduino Microcontroller with RB-Dfr483 (ph meter) looks fairly good, although a bit pricey. right now i’m looking for a cheap display that will be compatible with current software and board.

Any recommendations?

For reference my current build is

RB-Dfr-483 - Gravity analog PH meter
RB-Ard-34 - Arduino R3 microcontroller
RB-Oel-24 - Battery holder

Hi,

What do you want to display on this screen exactly ?

You have a lot of options compatible with an Arduino. A simple option would be to use a 16 x 2 LCD:

But it takes quite a bit of pins from the Arduino, you could go for an I2C screen:

You can also go for a shield version, this one includes a joystick and a buttons if you want to navigate in a menu:

Hope this helps,

Hi,

Thank you for the options.

I’m looking to display PH readings from RB-DFR-483 . Nothing too technical.

On a related note, where would you install the software for this design?

Thanks again.
