i no understand this analog Read functino good i have code analogRead A0 and then i mapping this to 0,1023 to 2-14 (ph value)
and potentiometer move come ok, o-1023 is 2-14 this is ok, but how i change value ?
now out come serial monitor full number only one decimal, mean out come only 2-14.
but how change code come out 2,1 or 5,3 or 12,6 one decimal more ?

some say to me other forum use float but i no understand all float anythink, i no need calculate this other numbers i need only this map to 2-14 and more decimal. how ?

sorry my bad englsih but finnis local section this forum no have help, and others net no have finnish language help, englsih not have good for me.

Sketch uses 3,888 bytes (12%) of program storage space. Maximum is 30,720 bytes.
Global variables use 222 bytes (10%) of dynamic memory, leaving 1,826 bytes for local variables. Maximum is 2,048 bytes.

My way:

Sketch uses 2,732 bytes (8%) of program storage space. Maximum is 30,720 bytes.
Global variables use 206 bytes (10%) of dynamic memory, leaving 1,842 bytes for local variables. Maximum is 2,048 bytes.

For the same result.

I don't know: does the OP then want to use that pH for any further calculations?
