In 2012, when I completed my undergraduate degree at Cornell University, I had a last minute idea to put an LED array on my graduation mortar board. The night before graduation I wired up a bunch of LEDs to a protoboard and an Arduino. The resulting product worked well, and garnered all kinds of excited remarks from friends and onlookers. But, it wasn’t bright enough in the outdoor sunlight, and it left me yearning to do something a bit more … intense.
Lucky for me, I stayed at Cornell for a fifth year to get my Masters degree in Electrical Engineering, and I therefore got to graduate again. This time, I was determined to do something over-the-top. Utilizing the super-high-intensity LED circuit board that I had designed for my masters thesis on Hybrid Fiber Optic LED Lighting, I built a web-connected LED graduation cap that would be truly ridiculous. Graduations can be a bit boring, so I wanted to develop an interactive platform (on my head) that others could fiddle with during the ceremonies. And thus, the “Control my Cap” project was born.

Adafruit Blue&White 16×2 LCD+Keypad Kit for Raspberry Pi – This new Adafruit Pi Plate makes it easy to use a blue and white 16×2 Character LCD. We really like the 16×2 Character LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 1 to control the backlight for a total of 7 pins. That’s nearly all the GPIO available on a Pi!
