Hello I am new to posting and have searched on the site for setting up a PH meter with XOD. Is this Possible? I have noticed there are a couple other posts but none of them have a clear response on how to actually make the meter accurate. I am using the PH probe from the Arduino store made by DFROBOT v1.1. I am using either a analog read node or gp2y nodes to get a voltage but cannot figure out how to multiply, average, divide my way to an accurate readout. any hints or suggestions as to what to try. I am fairly new to XOD (month or two) and any ideas would be greatly appreciated.
