tutorial – Kate Ringland, PhD

This week was a short week because of the July 4th holiday. I spent the week refining my project. I put together a list of supplies I would need to build an NFC reader and the tags to put into clothing. Sadly, a lot of the online stores did not have the components in stock.

In the meantime, I examined an already built RFID reader that was made by another graduate student last spring.

It was great to be able to see how someone else put a system together with different components. This system used a battery, an Arduino Pro Mini, a bluetooth controller, and a RFID antenna mounted on the outside of the box.

I also helped in the production of a tutorial video. The video is for people who will be participating in a study using an iPhone app called VizWiz. Learning how to make a video was a lot of fun. My main role was narration, which was a new experience for me.

I cannot believe how quickly this internship is going by! The first month is already over! June ended with a severe thunderstorm that left my apartment building without power from 11pm to noon the next day. The weather certainly is a lot bigger here than in the Pacific Northwest.

Last week, I endeavored to play with my Arduino Uno some more. I followed through the tutorials first. This mostly consisted of hooking up LEDs and getting them to do different things (blink and so forth). It doesn’t sound very exciting, but trust me, it is. Here are some pictures from the tutorials:

This was with one LED hooked up.

These LEDs were flashing at different rates thanks to the program I wrote.

The culmination of the tutorials was to have the LED be controlled by a push button.

After I was feeling fairly confident about working with the tutorial, I moved on to the LCD Screen Kit, kindly provided by Amy. I was able to get it all soldered together. And I had it working with the program at first, but then something went wrong and I’m still working on getting it fixed. It’s taking the input from the computer and garbling it, as you will see in the pictures.

LCD Message Garbled

There is a bit more work to do figuring out how to ungarble the message. This week I’ll be turning my attention to RFID and NFC scanners and tags.
