本文使用TinkerCAD Circuits來示範 LED、按鈕(PushButton)、壓電式蜂鳴器(Piezo)的綜合應用：「搶答器」，每個按鈕有對應的LED燈與聲音。
This is an application: "Three Responders system". The application uses LEDs, push buttons and a piezo to implement the system. Each push button has its own tone and turn on a LEDs when the push button is pressed.
