Power Button 1

Power Button 1 brings you an effective way to automatically start/stop the external hardware associated with a desktop application just in one click, as you usually start a desktop application (such as winamp or windows media player). For example, when you click the desktop icon to start your media player, Power Button will first start the external hardware, such as amp speakers, dim the lights then start your application all in one click.

Same, when you close your application, the hardware will revert to the initial setup (turn off speakers, bright the lights. It's a client-server design, which will also allow you to control the hardware remotely.
