Week 2

Activity: Listing of Project's Components

Objective(s): To list down all the components of the project hardware.

Consequently, after the research of the affiliated project title has been done, we managed to fathom the rough overview of the project we are about to develop. To make a review on the related previous research on thumbprint development is certainly not an easy task since we have to understand the objectives of the projects and make comparison of each existing projects. Thus, we came out with the circuit diagrams and the basic connection of each main parts of the project. Only then, we proceeded to the next procedure of the project development which is to list down all the project hardware. 

We discovered that in order for the project to function, it ought to be supplied with at least a 5V DC input. The most compatible microcontroller for this project is the PIC16F876A and the fingerprint module is the SN-FPR-UART Fingerprint Reader. For the project output, it requires the 2x16 character LCD display, a buzzer and LEDs.

The project is mainly constructed by 4 major parts which are:

1. Fingerprint module
2. Microcontroller (PIC16F876A as for this project)
3. Power source circuit (5V or any sufficient voltage to turn on the project)
4. LCD display (2x16 character)

Proceedingly, based on the outcomes of the project research, we are able to come out with the list of components for the project hardware from the circuit diagrams obtained. However, listing down the components is a very crucial task because error in choosing the right components for the circuit will conduct to the failure of the project. We documented the component list into a soft copy for our future reference. 

Result/Analysis:

Circuit diagrams:

5V supply circuit 

Microcontroller input circuit

List of components:

Conclusion:

In conclusion, previous project analysis is necessarily significant for us to come out with circuit diagrams and getting the rough picture of how the project will be. Meanwhile, the circuit diagram is essential for us to produce the list of project components and hardware. By having the list we shall be able to make the purchase afterwards.
