Made for graduation

I designed and programmed this pin to celebrate graduating from ITP, bringing together the electronics and programming skills I learned during my master’s degree.

The custom PCB carries an ATtiny microcontroller, a NeoPixel and LEDs, with slide and tactile switches and CR2032 batteries. I wore it to graduation.
