Second week

 In the second week, our group are going to achieve these aims:
1) Create a bluetooth app to control the system;
2) Complete the password and fingerprint parts of the door system;
3) Use the LCD to test the fingerprint part;
4) Test the system controlled by the sound;
5) Find methods to test the alarm sensor system.

However, there were still some problem caused by the program , like the decibel setting .  But we decided a proper range finally. In addition, we found the mistake in the connection caused the problems in fingerprint system.

We planned to  design the structure of the home and connect the system together with generator next week.

Figure 1: Interface of the App
The Bluetooth system can control both LED lights and lights.The user could only use this app after registering and entering the right password. Each password represents an id. 

Figure 2: Connection of UNO
Use wires to connect the right interface on the UNO board with the component. There are small words next to the interface to show the function of it.

Figure 3: Fingerprint Sensor
After downloading the library of the fingerprint. Enroll it and store the fingerprints by putting the finger on the screen of the fingerprint sensor. It will be stored when putting the finger on the screen second times after the program shows it is matched. We can check it and the matching.

Figure 4: LCD screen
There should be some words on the screen but it did not shown in theis week.
