We got the SD Card Shield a week ago but didn't really have time to implement it since we were trying to work on other problems. So this weekend, I sat down and tried to get it working. It was a success! At first it was a pain as usual. But after reading some online documentation (thanks Arduino community!), I was able to get things working. We're using a 64MB sd card to save the accelerometer data on. It might seem small for today's standards but for some plain text its more than enough. I was wondering how the data would look on a graph. With the sd card recording the data from the accelerometer I did some shaking, slow turning, and jumping. The following image shows what the data looked like. It'll be interesting what filtering will do to the graph. But that's for next time!
Oh yea the waterproof case came in! We're really excited to get our hands on it but since none of us are on campus, we'll have to wait till tomorrow.
