Arduino Twister Spinner

Twister is the classic game from your childhood! The referee gives the spinner a whirl and the other players follow the steps on the mat... until one of them falls. The last remaining wins! 

Wouldn't it be more fun to have a modernized version of the Twister spinner? On this Arduino Twister Spinner, the arrow is replaced by LED lights, with a buffer that moves automatically. By pressing the button, the referee can decide when the buffer stops. The light will either show green, yellow, red, or blue next to the decided position (for example: a blue light next to "right foot"). By turning the Potentiometer, the referee can adjust the buffer speed!
