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.
