I put the two photodiodes into two voltage dividers and wired them into pins 4 and 5 of the PIC. The comparators of a PIC18F4620 (or 4685) can be used to avoid extra circuitry. | I put the two photodiodes into two voltage dividers and wired them into pins 4 and 5 of the PIC.

This is how to build the device the way *I* did it. It's not pretty (see photos) but works acceptably. It could be improved upon immensely if you have any actual construction skills, metalwork experience, access to a CNC mill, etc. | This is how to build the device the way *I* did it.
