This PCB (Printed Circuit Board) resembles the YouTube Play Button award that is given out to creators for reaching certain milestones such as 100,000, 1 million, and 10 million subscribers. When the switch is turned on, the user can scroll through 5 different modes by pressing the button on the top left corner. The first mode leaves all the LED's OFF, the second is silver (100,000 subs), the third is gold (1 million subs), the fourth is a sparkling diamond effect (10 million subs), and the fifth, just to match the board color, is all red.
