This project is about displaying various three-letter airport codes in the ESP32. The artistic vision for this project is the idea of the relationship between home and airport codes. We are all familiar with air travel, and most of us rely on it to transport us from one place to another. This project was meant to be installed at Columbia University in New York City. However, I thought most students might not be from New York and call a city somewhere else around the world home instead. I envisioned a student walking by and seeing those three-letter airport codes, and hopefully, it might remind them of home or an unforgettable trip in that location.

I used different colors to show the codes. I used blue to denote North and South American airports, red for Asia, and yellow for Europe. I also used green for airports that I have been to. I decided to display the top 30 airports in the world. I wanted to reach as many people as possible by displaying the top 30 airports by passenger volume. I used different font sizes to differentiate. The top 10 airports have the biggest font size, then the top 20 airports, then the top 30 airports with the smallest font size. I kept the font size of the airports I visited as the smallest font.

The biggest technical issue was trying to upload the code into the ESP32. There was a problem with uploading the code using a Mac for some reason. I had to install certain drivers to my Mac to try and make it work. Ultimately, I borrowed a Windows PC to upload it without installing additional drivers, and it worked. Another issue was with the battery since it was defective and fried the ESP32 when I tried to connect it to one of its pins. This means I could not properly participate in the installation during class as I had to wait to receive a new ESP32 and upload the code again. Thus, the visual documentation was done at home instead.
