Can Arduino Mega 1280 get input from more than 16 potentiometers?
The Arduino Mega 1280 has 16 analog inputs, can the digital in/out be used to get data from potentiometers?
I need to get data from 25 potentiometers.

You can use a few digital outputs and an external analog multiplexer to switch multiple analog sources to a single analog input of the Arduino. The Arduino's analog inputs do the same by the way, they just have an internal multiplexer.
