This app tracks the activities of Fluffy (or any three-headed dog). Hagrid has a tough time taking care of all of his monster friends! This application helps Hagrid check on Fluffy (his three-headed dog) and see whether or not he is awake and blocking the trapdoor (that leads to the Sorcerer's Stone). If Fluffy has not slept in a while, Hagrid can tell the device to play music from the application and help Fluffy fall asleep! Hagrid can then save the device battery by turning off the music once Fluffy has fallen asleep. The application consists of a "Refresh" button and a "Music On/Off" button. When the "Refresh" button is pressed, the application gets data from the petfeeder device and displays it on the screen. Each time the "Refresh" button is pressed, the most current data appears. When the music button is pressed, the mobile app tells the device to start playing music. Throughout this, the device is receiving data from the hardware simulator that shows whether or not Fluffy is asleep and whether or not the trapdoor is protected.
