Week Fourteen

Objective:

•  To present about our Final Year Project
•  To make Final Report

Procedures:

This week we we had doe the presentation for our project. Our project assessor are Mdm Zarith Liyana & Mdm Zabariah. Here a few picture during the day.

With our assessors

We also start making Final Report because we need to submit the draft to our supervisor by this week. So, here the end of my Final Year Project title "Development of Health Monitoring Shoes".

Week Thirteen

Objectives:

• To troubleshoot circuit and coding
• To make casing for circuit and project
• To make a poster about our project

Procedure:

We troubleshooted the circuit, one LED had been replaced. We borrowed PIC burner from our senior to burn the coding into the PIC. After we had burn the coding, we try run the circuit and the circuit is successful. Every project have limitation, our project limitation is the sensor will keep counting when there no pressure on it because we had program the sensor to detect step when the user lift heir leg. This to avoid from the sensor keep counting step when the user stop walking if the sensor set to count step when there have pressure on it.

Then we had make casing for the circuit. The transmitter circuit need to be attached to the user leg.

We also done our poster for next week presentation days for Final Year Project. Below is our poster.

Week Twelve

Objective:

• To buy component that needed to build circuit
• To construct circuit based on simulation

Procedure:

This week we went to Jalan Pasar to buy components and takes our sensor that been  order. We still used the simulation circuit as our circuit event the simulation not running well. So, here is the list of our components:

1. Resistor 
2. Capacitor
3. PIC16F877A 
4. LCD
5. LED 
6. Bluetooth Module
7. Force Sensitive Resistance
8. Push Button
9. Battery 9V
10. Voltage Regulator
11. 4Mhz Resonator
12. Rectifier Regulator
13. PCB Board

After that, we design the PCB of our project circuit that we also used Proteus. We printed the PCB layout on glossy paper. To attach the ink of circuit layout to the PCB board, we ironed the paper to the PCB between 8 to 10 minutes. After ironed, the PCB needed to be soaked and shaken in a Ferrite Chloride to remove the unused copper. After finished, we need to make sure that all the connection of line in good condition. If have any line disconnect, just add the connection with marker pen. We drilled holes at the PCB board to put component's leg.Then, we arranged the circuit according to the simulation and solder the component .

Week Eleven

Objective:

• To complete the simulation for the circuit
• To adjust the coding according to the circuit that been simulated

Procedure:

This week we completed our simulation in Proteus. Bluetooth does not have in the list of component in the Proteus so we download file to add Bluetooth in list of component in the Proteus. Here is the link to download the file for Bluetooth : Bluetooth for Proteus

Before this we just connect both of the PIC tx and rx leg with jumper wire, so now we already replaced it with Bluetooth in the Proteus.

To completing the coding, we asked help from my partner's cousin that have more experiences in doing microcontroller to combine codings that we had found before this. Finally the coding was completed. To test either the project success or not, we try to combine the coding in the Proteus. When we ran the circuit, all the connection working but the LCD did not display anything. The LCD did have connection, maybe because not all pin of the component have in the simulation.

Week Ten

Objective:

• To learn how to write final report/ thesis

Procedure:

This week we have class for the final report writing that handle by Miss Pusparini Dewi bin Abd. Aziz at TTL1,Unikl BMI from 2.30pm until 5.30 pm. Distribution of percentage for the final report are:

1. Abstract (10%)
2. Introduction (10%)
3. Literature Review (10%)
4. Methodology (20%)
5. Result & Discussion (30%)
6. Conclusion & Future Development (10%)
7. Organization/Format (10%) 

They also provide details of final report format which contains about font type and size, margin of page, spacing and etc. Here I attached a picture and link for example guideline to write final report.

• FYP Final Report

Week Nine

Objective:

• To find datasheet for new component
• To order sensor

Procedure:

For this week, we need to find data sheet for our new component  which are Force Sensitive Resistance and Bluetooth HC-05 & HC-06.

• Bluetooth Datasheet
• FSR Datasheet

When we went to Jalan Pasar to survey price for our sensor, most of the component's shop does not sell FSR. Finally we found a shop that sells the sensor but we need to order because they need to order from supplier. So, we order our sensor.

Week Eight

Objective:

• To decide new component to replaced

Procedure:

After been studied about RF Module and accelerometer, we decided to change to other better component. After been studied, RF Module contain many noise and quite hard to find coding, so we decided to change to Bluetooth. It can transmits data in range of 2.48Mhz so higher than RF Module.

Besides, we also decided to change sensor from accelerometer to Force Sensitive Resistance (FSR). This because some characteristics of the FSR is better than accelerometer.  It have thin and flexible surface so it suitable with our project to put under shoe's insole. Hence, the price also affordable compared to accelerometer.

Week Seven

Objectives:

• To search coding that related with our project

Procedure:

In this week we had studied how to write coding and how using MPLAB software.We using MPLAB because it can combine with simulation from Proteus. This is for use to test either the coding can run on the circuit. So, we had searched coding part by part such as coding of push button, RF Module for the transmitter and receiver, LCD and for the sensor.

Week Six

Objectives:

• To check the simulation with our supervisor
• To do correction that needed with our simulation

Procedure:

When we have already finished the simulation last week, we need to check the simulation with supervisor. After we check the simulation with the supervisor, we need to do correction with our simulation circuit. In the simulation does not have component of our sensor. 

Then for the sensor, our supervisor suggested to put push button to represent sensor in simulation. After that we ask other people that have more experience, they said replace the sensor with analogue input.

Week Five

Objectives:

• To simulate of the project's circuit

Procedure:

By using Proteus, we have to design a circuit and run the simulation to ensure the circuit run successfully before we construct the circuit on board. During doing the simulation, some of the component not found such as the Radio Frequency (RF) Module and the sensor. For the Bluetooth, we just connect between two microcontroller PIC's leg number 25 and 26 that for transmitter and receiver.

Objectives:

• To make simulation for our project
• To make final decision for the sensor

Procedure:


Result and analysis:

Week Four

Objectives:

• To find the way to relate sensor and calories burn
• To know how the sensor will detect the footsteps

Procedure:

Accelerometer basically using three-axis signal input which are X-axis, Y-axis and Z-axis. It was noted that each distinct step was always characterized and count when by two acceleration on the X-axis along with one steep deceleration in Z-axis as shown below.

When accelerometer detected footstep and it will send to microcontroller to do calculation of calories burn.

Week Three

Objectives:

• To find datasheet for all of the sensor that being used in existing project
• To choose the most suitable sensor for our project

Procedure:

This week need to find datasheet for all of the sensor that being used in existing project. The sensor that been used in existing project is accelerometer, piezoelectric and FSR. After all datasheet been studied, accelerometer had been chosen because two of three of our references articles using accelerometer.

Week Two

Objective:

• To find the equation for calories burn by using footsteps

Procedure:

This week we need to find formula to calculate calories burn by using footstep. So, the simplest equation that we got is from Calories burn calculation . In this formula need to have weight in pound (lbs). To find calories burned per mile = 0.57 x weight. = calories per mile. Steps per mile assumed as 2000 steps. So, to get calories burn for each step = (0.57 x weight) / 2000  .

Week One

Objective:

• To find three journals that related to our project
• To study the hardware and software that used in their project

Procedure:
We had google articles that related with our project and article that we can refer to make our project. The first article we got article 1. This project using PIC16F684 as the microcontroller,Xbee as medium for data transfer and accelerometer MMA7660FC as the sensor to detect steps.

Second article that we got is article 2 . This project using AT Mega644V MCU  as microcontroller, the RZ502 wireless module  as the data medium and KXP74  tri-axis digital accelerometer.

Lastly, the article from past fyp project by our senior, Mohd Fadzli Mohd Fuzi which entitle "Pedometer". In this project, it used Arduino Nano as the microcontroller, Bluetooth V3 as the data transfer and Force Sensitive Resistance (FSR) sensor to detect footstep.
