Hey again..
well.. this is something. I wrote a sketch before that allowed me to calibrate the sensors by pressing a hardware button. I can't for the life of me remember what code I used. The instructions say PH:cal,mid,7 for example, but when I add that to my sketch I get "cal was not defined in this scope".. so I know the syntax is wrong.
Anyone know what command I can put in my code to trigger a calibration for an ezo sensor?
