06 December '17- Project 3- Rocket Payload

Project 3:
Our lab group consisted of Matthew, Richard, and I.  we decided to utilize the MPU 9255 9 axis sensor along with an SD card to store the data and an arduino Nano to run out program on.  We were initially given an arduino micro but quickly found out we did not have enough storage to fit our entire code onto.  Once we could fit our program on the Nano, we began to put all the sensors together and start soldering.  I initially thought it would be better to solder everything onto a perforated board.  Professor mason advised that it would be easier to solder everything directly to the board directly without having to use perforated board.  I continued on my initial plan of using the board and quickly understood why he suggested against it.  The board was insufficient in keeping any sort of solder properly secured onto it and also the pins soldered onto the arduino didn't absorb any solder when heated up.  So, after having most of the components on the perforated board i had to discard of the pins and find another Nano to use since the pins would not unsolder.  After lots of desoldering and soldering the payload was tested out with the final iteration of the code.  At first it seemed fine but realize there needed to be some modifications to account for certain values.  On launch day, the class was at a mad scramble to finishing packaging the rocket payloads, finding center of gravity, adding nose weight, and folding parachutes.  At the end of the day everyone had a successful launch and every group was able to successfully retrieve data from the payloads.

(we had took a picture f the error that  kept popping up when trying to upload the program; problem was the usb cable we were using)
