If you want to guard your phone, tablet, laptop, drone, Cozmo, Vector, Jibo, money, etc away from your sibling, (or if you just want your sibling away), you came to the right project! To start, set your volume to 100% (so you could hear if anybody got in) then click the green flag. Then get out of your room, and if your sibling (or anything else) comes in your room, it'll go WAA WAA WAA like a car alarm.
