Purpose:

The purpose was to accomplish the task of reading more than six analog sensors.Even though we still only used six, it gave us the opportunity to use more. It was also to get us comportable with the multiplexing structure and will allow us to use multiplexing strategies for future projects.

Procedure:

First we breadboarded our circuit using the multiplexer. We kept the Processing code exactly the same but we changed the Arduino code a considerable amount to allow for multiplexing. After we did a few touch-ups on our processing code for a bette aesthetic appearance.

References were minimal other than the information given from our teacher. However the project is still loosely based off of Serial Communications Using Processing 2 post. Click here to view those references.
