As musician in the Cal Band of UC Berkeley, I am given the freedom to develop my straw hat as part of our uniform for smaller performances. Naturally, I took this opportunity to display my passion for technology.

Initially, I used a breadboard in order to connect the LEDs and potentiometers. The potentiometer then controlled the speed of how the lights would flash. However, noticing that this was not very stable and required a lot of wires, I moved on to using a PCB board.

In addition, I also affixed a fan powered by a DC motor, which gets it power from a battery pack. On the side of my hat, there is also a switch to turn the fan on and off.
The beauty of Arduino is that the circuit board easily draws power from a battery pack that is zip-tied to the back of my hat!
Using a printed circuit board, I was able to connect all the ground connections to one port, and simply divert power to all the LEDs by one single wire, and using a button that switches between the modes of how the LEDs would flash!
