Fourth week

In the fourth week, we have completed the whole connection, there are something else we have done shown in the following:
1) Complete the design of the home;
2) Test the program of LCD part;
3) Set the circuit in the model.

Actually, the fingerprint system had many issues when it was tested in the circuit connected. Additionally, the program for the LCD part went wrong, there was nothing shown on the screen. At first, we thought the reason is that the model number is  different with that in the program. But after testing for many times, the mistake was found in the connection of the UNO board and the LCD.  For the design, the material for the home was  not so satisfied as we hoped. Sometimes it is difficult to keep the setting tidy and functionality togther.

Next week we are going to complete the setting and start to do the poster. The project will be finsihed in the next week.

Figure 1: Final connection of circuits
We changed some connections because of the  combination and use only one UNO board in this system. The system worked when testing and it will be put in the model.

Figure 1: First Step of the construction
Each part of the model was printed by the machine and we decided to connect each part using glue which was provided. In addition, we would put a  carton on the bottom of the model to hide the circuit. The system was not tested in this week.
