WF32 Controlled iPad Mount Wins a Trophy!


As you may or may not remember, I participated in the senior design competition at WSU with two other Electrical Engineering students, sponsored by Digilent. We created a WiFi controlled iPad mount meant to assist the sight impaired find lost items, and we used the WF32 WiFi capable PIC32 microcontroller. At long last, I’m sure you are dying to know the results of the poster competition; our team got second place! Here we are with the trophy.

Here's us with the trophy.

Despite having an awesome end prototype, our project had some features that we would have loved to have had implemented given more time. Right now our project works as a sight assistant, but only in on room within the range of movement of the servos and stepper motor.

In our project, we only used pins 42 – 28 of the WF32‘s digital output pins. As you can see from the pin diagram below, there are many more. This definitely allows for the possibility of more motors, and complete mobility.

About Author

When I started school I wasn’t interested in any of things I’m passionate about now. In fact originally I started out wanting to study art. But then I decided I didn’t want to have people telling me what to create, so I changed to music. Then I decided I didn’t want to ruin a hobby by making it my career. At the same time my Physics class was teaching a unit on the physics of music, and I thought that was way interesting, so I changed to physics. Then by the time physics was over I decided that the coolest part of physics was electricity and magnetism, and I may as well get a degree that transfers directly into a career. So while all this was happening, I was attending Shoreline Community College, and during that time I found my passion, or rather presented itself repeatedly, until I realized, maybe I should take a hint from the universe. While at community college, I was asked to help at the high school by tutoring chemistry students. Then I was asked to help at the elementary school by being a math Olympiad coach. I continued both because I found I really enjoyed it. I also had an opportunity, and was hired to be a tutor in the Math Learning Center at the Community College, a job I really loved. At the same time I was working as a Nanny, which I had been doing for several years, the main reason because I could and would answer the hard questions the kids asked honestly (i.e. why is the sky blue). I then was recommended by the patrons of the MLC to the transfer tutoring center (private tutoring,) and developed a wait list of students. Through all these opportunities at some point I realized that I loved watching people go from totally lost, to masters of a subject. I was also forced to admit that having all these opportunities continually renewed, I must have been somewhat good at it. So I decided I wanted to teach, which fits with my mission oriented personality. I saw a serious lack of passionate ECE professors in the institutions I attended. At WSU I continued this trend by being ask to TA for computer science and electrical engineering, being a TA for a total of 4 semesters. This continued by getting an amazing opportunity in my first semester at Washington State University to work at Digilent, an educational company. So even if I didn’t want to teach, turns out I can’t avoid it. Luckily it is my main passion.
