Lab 0.5 - The Bike Light Extension

Due: 10 September 2012


In this extension, you will build upon the bike light from Lab 0 by adding an analog light sensor - a photoresistor - to your light.  You will make your bike light react to the presence or absence of light, much like “automatic car headlights” when entering a tunnel.  You can make this as simple or complex as you see fit.

Lab 0, and this extension, should be written up by class time on Monday.


  Photoresistors act like a resistor, with a variable resistance based on the brightness.  How could you measure that?
