Hi, Light sensors are about the easiest of any type to hook to a HandyBoard.

First, try this: (URL) that won't do it for you, and you can get I/O control over your PC, you can use the SPI port at J6 for some very fast transfers.

Use the encoder routines from the HB web site: (URL) these, you can use any of the analog ports (i.e., you don't have to use ports 0 and 1 first).

Voltage and resistance have no relation to each other - they are two different things.
