Arduino - BLUETOOTH & ANDROID PIR ALARM With Call and Sms Functions!

Hello world! Today i made a android app that communicates with a arduino using the HC-06 Bluetooth module for a PIR Motion sensor GSM Alarm. You can set 1 phone number to the DATABASE that needs to be called when movement is detected. When movement is detected it will call you and you can listen what is happening in your home, If you missed the call you can send a SMS with the command "Call me" (it is case sensitive, so use capital C). You can also send a SMS command with "Disconnect" and the bluetooth module will disconnect. For the Schematic, Arduino Code, Android APP & Parts list follow the next step.

NOTE: You need to take a few steps for the APP to operate properly and you need to connect the Phone to a Charger.

Follow these next steps on your Android phone. (This might be different on your phone, check google on how to keep your phone screen awake)

Settings, go to call, extra settings, turn off proximity sensor. (Turns off screen during calls when set to on, and we want the screen to be on during calls)
Settings, Location & security, setup screen lock to none.
Settings, Applications, development, turn on standby or might be named stay awake on your phone (keeps screen on during Charging)
Plug in a USB Cable & keep the phone plugged in.
