Rushing for Submission

So 13th Dec its the submission day, we really very worry about couldn't finish on time. And also we did apply to stay overnight tonight, but it comes out decline the approver from the department, so we don't have much time . But we will try our very best, and it because of Wednesday Fab Lab is having classes, and everyone is waiting for 3Dprint and  Laser cut, so come out we have to wait everybody to finish their stuff then we only can use it.

For the coding part, we only have around 1 week to explore on processing, and we still could not get any audio play by trigger. I could not really get help from my classmates because I'm the only one who are using processing and no one else know how to use it, so we get help from our senior, but at the end it is still not working. We have trouble on checking the code during the whole process because of the unstable connection of Arduino port, but at the end we still could not read signal from Arduino on Processing.

Submission

The time submission is 4.00pm. But we still left more parts haven't done. 

The prior of today is to settle the code and wire everything up.

Before 4pm, we asked our lecturer about how to read signal from Arduino in processing, turns out, we don't need to use serial communication since our project are just using processing to output the sound, we change the code to Serial read, which is very simple and not confusing, and for the first we receive the signal from Arduino in Processing!

Submission extended one more week because at 4pm, most of us have not done our projects.
