Play with Light Resistance

[Light Challenge 2 Fritzing File](https://drive.google.com/open?id=0B13oE93nzkTCSk9yV2lZUGFnTlk) Let's already try a really fun sensor to control our light. A Light Dependent Resistor or LDR looks like a little solar panel. It measures the amount of light it can sense and we can use that information to affect an output like a light. Ever used a night light at home? We can make our own version or cause the output to react in a variety of ways. 1 Arduino 1 USB cable 1 Breadboard 1 LED 1 330 ohms resistor 1 LDR Photocell 1 10K ohms resistor (or corresponding resistor to work with your LDR) 6 jumper wires <span style="display:block; text-align:center;"><iframe width="450" height="380" src="https://123d.circuits.io/circuits/2120541-light-challenge-2/embed" frameborder="0" marginwidth="0" marginheight="0" scrolling="no"></iframe></span>
