Lab 2 - Testing, Testing, 1, 2...

Due: 3/4 October 2013


  After Labs 0 and 1, you’ve encountered Arduino programming, digital and analog input/output, using libraries, servo motor control, and two-way communication with a PC.


  In this lab, you will expand your familiarity with the capabilities of the Arduino microcontroller by building a laboratory testing rig.  The test setup will measure the opacity of materials in at least two petri dishes.  Such a system has applications in measuring water clarity, measuring bacterial growth, or any number of other areas.

  When complete, the device will:

Any other aspects you deem worthwhile (plotting, data archiving) are up to you to decide.

The requirements of the project are as follows (and designed to leave room for creativity):


  Your completed system is the first deliverable.  Think about what an actual scientific user (or yourself) would want to see.  Consider the mechanical system, the data logging format, what data you might want to see in live time, and any other aspects you deem relevant.

  Please hand in a lab report at the completion of this lab (based on the lab format handout).

Your report should contain, at a minimum:
