Final Year Project 2 Logbook/Blog

Task: Updating Chapter 3 at the report as chapter 2 has been completed. In Chapter 3, the components and methods will be describing in the project. This chapter covers about block diagram, flowchart of project, the software and list of components and cost estimation this project. This chapter will detail more about each and every component’s function in this project. From the components, the explanation of coding will be explained too. This method shows on how to implement the coding with the component required to build up the project. Block Diagram of the Project The block diagram shows the flow of the project works, started from input, microprocessor and output. At the toggle switch, it has designed with the battery when blind persons only want the know the status of the heart rate via earphone.         Once the toggle switch has been turned on, Arduino Uno starts to process the information from the pulse sensor, and then with EasyMP3 Shield. Ea...

Task: Completing Chapter 1 1.1 Introduction Health is a physical, mental and social well-being state in its entirety. A people need a healthy diet and must exercise regularly for a healthy life cycle. People also have to live in a nice shelter, sleep well and have good hygiene habits.          When one or more organs or systems of the body are adversely affected as they are interrupted in their normal functioning, that means their body are not healthy and have a disease. Disease means the body feel unwell or body dysfunction. That is why people need to be aware with their health. The most important thing is to check on body heart rate.         Heart rate device is really popular nowadays. People often use it during working, resting and also exercising. Even though most country has people with health problem, not forget there are also people that really care about their health by keep themselves fit most of the time. However, mos...

FYP 2 Exhibition Day Semester July 2019 Day: Wednesday Date: 9 Oct 2019 Time: 8:00 am - 2:00 pm  Venue: Gemilang Hall UniKL BMI The presenter and project Poster of the Project

On 2 Oct 2019, a FYP 2 Briefing had been covering: FYP 2 Exhibition Day (Tips & Tricks) and Submission of Progress Report, Final Report & Technical Paper. Students were able to know the tips and how to present their projects during Exhibition Day. The speaker also brief on Submission of Progress Report, Final Report & Technical Paper. Next, a sketch has been made for this project. Google Sketch Up used to draw the casing of the project. A sketch need to be provided some Braille cell for guidance to the blind people.   Left View of the Project Right View of the Project

Coding for ESP8266 NodeMCU also needed to send heart rate rate to the IoT. Since ThingSpeak has been selected for the IoT platform, the ThingSpeak library should be included in Arduino IDE. To connect the ESP8266 NodeMCU to ThingSpeak, the username and password of the Internet connection need to be the same so that the data can be transferred. In the coding, channel identification and “write API keys” should be filled so that ThingSpeak could be connected. Example of ThingSpeak Coding After edit the code, the heart rate data can be sent to the Thingspeak. The results were give a huge different as the pulse sensor was so sensitive. Real Time Heart Rate Measurement data displayed on ThingSpeak

To set up ESP8266 with pulse sensor, a voltage regulator circuit need to be set up. In this diagram, a 10k ohm and 4.7k ohm resistor were used along with 10uF capacitor. Voltage regulator has been made in this circuit to make it operate within 3.3V. Figure and table below shows the connection between ESP8266 NodeMCU with pulse sensor, resistor and capacitor. Since the ESP8266 NodeMCU and pulse sensor component were not available in Fritzing skecting, the components were substitute with the nearly same component. After set up the circuit, the ESP8266 NodeMCU will be connected with th USB cable. Connection of Pulse Sensor, ESP8266 with Voltage Regulator The following shows the main connection and wire connection of the circuit; Connection                 Wire Connection Pulse Sensor (GND)------ESP8266 (GND) Pulse Sensor (VCC)------ESP8266 (Vs) Pulse Sensor (A0)---------4.7kohm 4.7kohm--------------------ESP8266 (A0) 1...

To save the data, Parallax Data Acquisition (PLX-DAQ) has been used with the help of Microsoft Excel. As some blind persons were computer literate, they can save the heart rate by their own. Before start, download PLX-DAQ and enable Active X and Macro on Microsoft Excel. Then put the following code in the Arduino IDE; i. Serial.println("CLEARDATA"); This line required to clears sheet starting from row 2. ii. Serial.println("CLEARSHEET"); This line has to clears sheet starting from row 1. iii. Serial.println("LABEL,Date,Time,Heart Beat,millis"); It defines four columns named "Date", "Time", "Timer", "Heart Beat" and "millis". This part can be edited according to the data obtained. iv. Serial.println( (String) "DATA,DATE,TIME," + myBPM + "," + millis() + ",AUTOSCROLL" ); Getting the data from the sensor to be included in the Excel. v. Serial.println("CELL...
