First week

In the first week, we are going to complete this activities:
1) Each group member completed the circuits they  are responsible for.
2) Considered how to connect bluetooth with the circuits and how to write the program for UNO board.
3)Discussed the problems.

Plan structure:

We connected the circuits for each system successfully but there are some difficulties in programming and bluetooth. Moreover, we were unfamiliar with some components like relayer shield. There are too many interfaces on UNO board, and we do not have enough knowlege of its function. Therefore, we could not prove the correctness of circuits. And it is inconvenient to test smoke alarm, we can not simulate the condition in the lab . To be brief, it was a good start, but there were many detailed things to think about.

Figure 1: Door System
The program for the password and fingerprint system is togther in one UNO board, so the door can be controlled by either the fingerprint sensor or password .

Figure 2： Window System
Window is controlled by a generator.

Figure 3: Light System
The light should be controlled by Bluetooth system and one of them which set outside the door should be  sound control.

Figure 4: Smoke Sensor System
This system acts a alarm to prevent fire.
