S2 Week 17

This is the last academic week before Aidilfitri break. For this week, I continued on the writing of my final report for completing the FYP2 course. Here, I would like to give my utmost gratitude and respect to my supervisor, Dr. Ahmad Sabry bin Mohamad. For 2 semesters under his tutelage, I have gained a lot of knowledge from him. He also showed a lot of patience to his students knowing that we are just undergraduates doing our best to complete a project. Thank you very much.

S2 Week 16

This week is the Industrial Day week. On this week, I made the final testings just in case and prepared the testing videos just in case the device malfunctions during presentation. I was advised to do this by senior students that have undergone their FYP2 course. Below is my final testing.

Alhamdulillah, I have presented and was able to answer all the questions asked to me by the assessors. The first to assess were 2 guests from industry. They both looked enthusiast by my project. The second assessor was a lecturer from UniKL BMI. She gave some suggestions on how she viewed my project, but nevertheless, I was able to answer her questions. 

S2 Week 15

For this week, it is filled with preparing the device for presentation and creating a poster for industrial day. Firstly, I would like to show the final product.

This is the result on the smartphone interface and the LCD display when connected. 

My poster for industrial day.

The poster clearly showed the whole flow of the project and explained in a simple way how the device works. 

S2 Week 14

On this week, I started on the full testing of my project. I chose a colleague that was healthy and tested on him. The subject muscle would be the biceps as the maximum voluntary contraction would give a high amplitude. The video can be found below :

First full testing video.

S2 Week 13

In this week, there was another briefing for Presentation Skills for Project Demonstration. It was presented by Mr. Zulhilmi bin Mustaffa. The briefing was great as it will prepare the students for the upcoming FYP2 presentation on Industrial Day. The date was set at 14.6.2017 which is week 6.

I tweaked the parameters for my coding to start recording the maximum value of the EMG signal after 2.75 mV. I did this as when the device is connected and the patient is at rest, the signal output would idle at around 1.5 mV. The testing muscle would be the biceps.

The Parameter coding.

S2 Week 12

In this week, I am going to show the coding used in my project.

Coding of my project.

For my software, I used 3 libraries, 

#include <Wire.h>  

#include <LiquidCrystal_I2C.h>

#include <SoftwareSerial.h>

Afterwards I set the I2C LCD display. Then, I set the Arduino to scan for analog input from the sensor. The HC 06 was used to interface any command to the smartphone. I am still in the testing phase and would like to set better parameters for gauging the signal from the sensor.

S2 Week 11

In this week, I started on the assembly of my device. Unfortunately, the phone that was used to record the assembly process malfunctioned and the data was lost. Nevertheless, I will tell of the process here.

1. I begin by assembling the device by having the Arduino Uno as the center.
2. Connected the pins from the AD8232 sensor to the respective pin on the Arduino.
3. Connected the I2C LCD to the Arduino.
4. Connected the HC06 bluetooth to the Arduino.
5. Connected the USB power line from the Arduino to a laptop.
6. Verified all components are working and light up.

Next step is the software part of the project. It will involve using the Arduino Sketch software can be downloaded here.
