I added switches to the fourth iteration of the passage of time. 1 rocker switch for on/off, 1 toggle switch which switches between 2 patterns, 1 momentary pushbutton switch that changes the pattern when the toggle switch is up. The switches are mounted on a separate short box with holes drilled using the dremel tool and attached to the bottom of the taller box. All the switches are hooked up to the Arduino using a breadboard.
