* Wire up a simple voltage divider using your potentiometer and a 10K resistor, conected to the 5V supply.
** How does Observe how the output voltage vary changes as you turn the knob? .(measure at the point between the potentiometer and the resistor) What is the highest voltage you can get? What is the lowest?** Now replace the 10K resistor with a 1K resistor and measure how the voltage changes as you turn the knob. What is the new lowest voltage you can get?

* Photoresistor as variable resistance
