This week, the week of November 11th, our group has made significant progress on our project. We met on Thursday, November 14th and decided to work on sections individually and then compile the work. We have finalized the design for the motor housing piece in SolidWorks and posted it to the blog. We also have begun the coding for the operation of the mechanism using the Arduino Board. This is just a basic code to start off and its purpose is to make the push buttons correspond with the LEDs. The construction of the wiring on the Arduino Board was also started this week, and the group has begun to understand how we plan to wire our mechanism. Furthermore, here is a link to the code thus far: https://github.com/RubeGoldberg/22.201-802-ChrisPeterEddie/wiki/Intial-Code#include--1, to comment on or if you have suggestions. It is also listed below.
