 Result/Analysis

MPLAB IDE v8.30

·         MPLAB IDE runs as a 32-bit application on MS Windows^®, is easy to use and includes a host of free software components for fast application development and super-charged debugging.

·         MPLAB IDE also serves as a single, unified graphical user interface for additional Microchip and third party software and hardware development tools.

Source Code

·         used as a method of communicating algorithms between people (e.g., code snippets in books). Such a language is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code, which can then be automatically translated to binary machine code that the computer can directly read and execute.

·         Most computer applications are distributed in a form that includes executable files, but not their source code, which is only useful to a computer programmer who wishes to understand or modify the program.

C Language

·         C is much closer to assembly language than are most other high-level languages. This closeness to the underlying machine language allows C programmers to write very efficient code.

·         Programmers around the world embrace C because it gives maximum control and efficiency to the programmer.

Budget

The expected cost should be the lead in the entire project making. This is to make sure that the expenditure for the project does not exceed the budget cost. The table below show estimated budget on the overall cost of the project.

A) Software
1.	PROTEUS ISIS (Student Demo version)	-
B) Stationary
1.	Papers	RM 30
2.	Printer ink	RM 10
3.	Photocopy	RM 20
4.	Binding	RM 20
C) Others
1.	Travelling expenses (Data collection)	RM 50
2.	IR Sensor & Alarm	RM 100

 Conclusions

From the conclusions in week 9

 -As conclusion, this is the main important that needed to do the project is a programming code and the estimation budget for this project. All of this  main item will make the process for this project will go smooth if anything according to plan.

Week 8

Title of Activity
-Research about Methodology.

Objective
- To know what method being used in this project and the function of each component.

Content/Procedure

-flowchart methodology
-Block Diagram.
-Explanation on each of the block diagram.
-Function on each block diagram.

Result/Analysis

Continue flowchart 2

Basic Model of the System

The block diagram depicts the total blue print of the proposed project. The total essence and the functioning of the project are represented in a single block diagram. The block diagram mainly consists of 4 parts

• LM358 Comparator
• Eye Blink Sensor
• LCD
• 16F877A Microcontroller
• Buzzer

                                                    block diagram for eye blink detector

IR Sensor

·         The transmitted signal is given to IR transmitter whenever the signal is high, the IR transmitter LED is conducting it passes the IR rays to the receiver.

·         The IR receiver is connected with comparator.

LM358 Comparator

·         The LM358 consist of two independent, high gains, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage.

16F877A Microcontroller

• Wide operating voltage rage (2.OV-S.SV).
• Programmable code protection.
• Power saving sleep mode.
• Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation.
• Self-reprogrammable under software control.

Buzzer

·         A buzzer or beeper is a  signaling device, usually electronic, typically used in automobiles, household appliances such as a microwave oven, or game shows

·         It most commonly consists of a number of switches or sensors connected to a control unit that determines if and which button was pushed or a preset time has lapsed, and usually illuminates a light on the appropriate button or control panel, and sounds a warning in the form of a continuous or intermittent buzzing or beeping sound.

Liquid Crystal Display (LCD)

·         The LCD display consists of two lines, 20 characters per line that is interfaced with the PIC16F73.

·         The display contains two internal byte-wide registers, one for commands (RS=0) and the second for characters to be displayed (RS=1).

Conclusions

From the conclusions in week8

A methodology is instantiated and materialized by a set of methods, techniques and tools. A tool is any instrument or apparatus that is necessary to the performance of some task. A methodology does not describe specific methods; nevertheless it does specify several processes that need to be followed.

Week 7

Title of Activity
-Continue on doing the research.

Objective
- To find a similar project and do some research on it.

Content/Procedure
-Information about the previous project.
-Some of the circuit that use in this research.

Result/Analysis
at this point i already done research the circuit...

The sensor is always ON, meaning that the IR led is constantly emitting light. this design more power consuming and is not optimized for high ranges. in this design, range can be from 1 to 10 cm, depending on the ambient light conditions...

As you can see the schematic is divided into 2 parts the sender and the receiver...  The sender is composed of an IR LED (D2) in series with a 470 Ohm resistor, yielding a forward current of 7.5 mA...  The receiver part is more complicated, the 2 resistors R5 and R6 form a voltage divider which provides 2.5V at the anode of the IR LED (here, this led will be used as a sensor). When IR light falls on the LED (D1), the voltage drop increases, the cathode's voltage of D1 may go as low as 1.4V or more, depending on the light intensity. This voltage drop can be

detected using an Op-Amp (operational Amplifier LM358). You will have to adjust the variable resistor (POT.) R8 so the the voltage at the positive input of the Op-Amp (pin No. 5) would be somewhere near 1.6 Volt. if you understand the functioning of Op-Amps, you will notice that the output will go High when the volt at the cathode of D1 drops under 1.6. So the output will be High when IR light is detected, which is the purpose of the receiver.

Conclusions

From the conclusions in week7

The get how to analysis of face images is a popular research area with applications such as face recognition, virtual tools, and human identification security systems. This project is focused on the localization of the eyes, which involves looking at the entire image of the face, and determining the position of the eyes by a self developed image-processing algorithm.
