I'm using the uno32 and the analogRead function seems to be scaled from 0 to 3.3V. Is there a way to change this to 0 to 5.0V?

Scale your reading as there's no way to change the 3V3 PIC32 into a 5V device :-)

You can you a [color=#0000BF]resistor voltage divider. [/color] Here is a calculator for values: [color=#0000BF][url]http://www.raltron.com/cust/tools/voltage_divider.asp[/url][/color]

If you have 10K (R1) and 18K (R2) resistors they will work fine.
