Step 6: Light Sensors

The eyes each include a light sensor in the pupil. Simply find sufficiently large but high gage wire and then solder a line for power onto the longer end of the sensor (if the ends are cut, you may want to test it first in a breadboard) and a shorter line for ground and data. Towards the end of the later wire, solder in another line for analog readings and a 2K ohm resistor with a line purely for ground on the other end. This should create a "Y" like split with one line coming in, one line coming directly out, and a final line with the resistor attached. Do this twice, one for each eye. We found it useful to attach headers to the ends of the wire.
