This summer I made something that I am really proud of! I illuminated a tutu with a LilyPad Arduino using only online resources. I was challenged to set aside traditional learning resources, which I wrote about in an earlier post.
I coded a simple sketch to illuminate the NeoPixels. Then I pulled in an example sketch from the NeoPixel library. The steps in coding are: write the sketch, verify it, then upload it. In my experience coding, if error messages come back at either the verify or upload stage, the sketch will not work.
I got a message when I attempted to upload my sketch that said, “User configuration file does not exist or is not a regular file, skipping.” In RED. That was one of approximately 60 lines in the error message.
So I researched. For hours, I read Internet help forums in which other Arduino Makers had reported the same error. From what I could find, it appeared that my version of Mac OS was not going to work with Arduino. I began to envision having to scrap this project and start over. I spent at least four hours reading and uninstalling and reinstalling the Arduino IDE. I even opened the Mac Terminal and considered manually inputting some instructions directly into the command line.
Then it happened. After hours of reading and more than a few tears shed, I found it. On the Arduino Product Forum, someone had written, “Don’t worry, it’s not an issue to have this message – it will use the supplied default. :)” The smiley face was really included in the forum post. I am sure I had read this message ten times. This time, though, I realized what it meant: my code would work, in spite of the error message. I tried one more time and it worked!
My troubles weren’t over, however. When I tried to switch from the Uno to the LilyPad, I discovered that my LilyPad had gotten broken so I ordered a new one. Once it arrived, I was finally able to switch from the Uno to the LilyPad and got my LilyPad to light up the NeoPixels.
Next, I connected all the NeoPixels to the LilyPad using wire and electrical tape. It would have been more elegant to use conductive thread but I made this choice in the interest of time.
Finally, I moved the LilyPad to battery power. I attached my daisy-chained NeoPixels and the LilyPad to the tutu. The results were lovely, and I was delighted.
As Jaymes Dec, teacher and Innovation Specialist says of digital tools, including Arduino, “I really want my students to lose their fear of failure,” (Burker, 2015, Loc 1731). I can attest to the fact that I truly thought I was about to fail during this project. In the end, I succeeded. I made something I didn’t know I could make and I learned a lot about microprocessors and myself in the process. Through persistence, I can figure out just about anything. And when something is so difficult that it hurts, overcoming is the sweetest success!
