* Wire up a simple voltage divider using your potentiometer and a 10K resistor, conected to the 5V supply.
** How does the output voltage vary as you turn the knob? (measure at the point between the potentiometer and the resistor)

* Photoresistor as variable resistance
** measure the "light" resistance of your photoresistor
