Finial Project- Week 2

Week Two!

Tuesday:

With the software ready to go, Holes were drilled on the spool I found last week to connect to the servo. Keep in mind, the servo is not continuous, so the diameter of the spool is the vital part of the success of the prototype. (reference to my week one blog post for better explanation) After testing, we realized that we needed to increase the diameter. I suggested putting piano wires all around the outer edge of the spool, Hanna suggested to hot glue a popsicle stick on the outer edge. Since it is a prototype we decided to use the hot glue instead. But having one stick does not increase the length of the wound up string as much as it would if the spool were circular. So we glued multiple sticks all around.

Our prototype worked but I still think the spool diameter is questionable.

Friday:

We received feedback from the CSC, one concern was that the flush warning was not long enough. Which is an easy fix. Another interesting point that was brought up was the flashing rate of the LED. I have programmed both the HIGH and LOW to decrease proportionally until it becomes too fast for our eyes to see. But from an outsider point of view, it seemed like there were three different lengths of flashing. I wonder why…

We received our package from Adafruit which means it’s time to turn this messy prototype into a functioning pretty little box. The first problem that arose was the button. Since the last button and the LED in the prototype are separate, the wiring is now slightly different. The LED isn’t the confusing part, what was confusing was the button, since the last button had four prongs and the new one had two that is responsible for the input. The button couldn’t work properly by the end of week two.
