Aaron and Kelly: Chair Progress

We are still hard at work trying to make our responsive chair! Sitting too long is, as recent studies have shown, We intend to create a chair that will time how long a person has been sitting, and tilt them forward after they've been sitting too long to encourage a well-deserved stretch break.

We've made some good progress on this front in the last week! Recently we disassembled our chair and then reassembled it without most of the springs, so now the back and seat can move without depressing the levers under the seat. Quick demo video:

Now that we have it freely moving, we can connect up our motor and Arduino onto the chair directly. Next step is figuring out how to best arrange the setup, and get our extremely confusing arduino four-way relay working.

We also experimented with our motor itself, to see just how much power we'll have and if the chair will be able to move at any relatively fast speed. Based on this, I don't think we need to worry.

We've been experimenting with the Arduino Metro timer library, and will be using this library to handle our timed actions as we move forward into the programming portion of our project.
