A rocker switch was used to select between Vibe (vibrate for 15 minutes, no lights or sound) and Car (the full effect). The Go! button allows the user to start or stop an action.

It looks at the state of the rocker switch and the start button to determine what to do. Once actuated the MP3 shield plays the track until completion. The LEDs and motor turn ON/OFF randomly every 30 and 60 seconds, respectively. There’s also a vibe-only mode that vibrates the chair for 15 minutes.
