I have a project in mind that will be a good beginner project.

The goal is to read in a voltage through a 8bit A/D, have the PIC take the voltage and look up a table in memory. This table will have the 'in' voltage value, and a corresponding 'out' value. Find the value, and select the value corresponding to the first. Then, output the voltage value (PWM?)

I need some help/pointers as to a beginning for the PIC selection and coding.
