 ### Other ideas
 Of course Arduino can be used many other ways. Add a PIR motion detector module from Ebay (under $2) and your computer wakes up from sleep when you walk to room. Just read PIR-sensor data pin and if it is 1, send some keyboard button (which normally does nothing) to computer so it wakes up. Or make info-board to your kitchen or hallway wall from old Android tablet and it turns on backlight only when someone goes to kitchen.
