Arduino Graffiti

The display, as of today

A few days ago, I decided to see what a little microcontroller like the Arduino could do if I connected it to the Internet. Using the LCD display from my stopwatch project, I decided to set up a display that would act as the world’s smallest graffiti wall. I set up a form on my web site where people could enter their two-line messages, and devised a way to get those messages to the Arduino via the Internet. I’m not entirely satisfied with the solution; I’ll probably continue to tinker.

Intrigued by the whole idea and unwilling to wait until I’d perfected the thing, I decided to announce it on Facebook and see what happened. I put the display next to my living room TV, plugged into a wired Ethernet port.

The responses were wholly entertaining. In fact, I was having trouble convincing myself to go to sleep because I’d miss some really funny stuff. So, I modified my php code to also log the entries as they were displayed.

Here they are, for your enjoyment. There are no dates or times, and no one knows who wrote these pearls of wisdom except the authors themselves.
