Android Arduino Bluetooth

This is an infrared motion sensor connected to an Arduino microcontroller. When motion is detected, the microcontroller communicates to a running Android application via Bluetooth to play a sound and show a notification. The notification is dismissed and the microcontroller is ready to detect the next movement. The alarm can be disabled for 1 minute from the application and if the connection is lost during use, a different sound will play.
