|Resistor 10 kΩ (stripes brown, black, orange, gold)|
|Jumper Wires (male to male)|
To try out this tutorial, you will need:
The photoresistor used has a dark resistance in excess of 200 kΩ and under bright light, the resistance falls to 1 or 2 kΩ. You can use other photoresistors, but you may need to change the value of the 10 kΩ resistor in order to get good resolution for your light measurements.
