Hey guys,
Would it be possible to make a electronic pH meter that would have 14 LEDs to indicate the pH of a solution it is placed into.
This would be hard because voltage would change with salinity as well as pH.
Salt in water would have a pH reading, but it is neutral.
Is it possible to make a simple pH meter? Any thoughts?
thanks.
