Activities :

1. Collection of Data - Waveform

📆 14 November 2019
📬 FYP Room, Level 2

📌 For this project, there are two alarms that must be collecting the data of the sound waveform which are the NIBP sound alarm and battery failure sound alarm. The data of NIBP sound alarm is collected by conducting 20 tests. Each test is observed by reading the frequency of the waveform for the full cycle and the positive width of the cycle. The serial monitor data calculated by the coding is also recorded. All of the data taken is captured using camera, the value of the reading is written in the Microsoft Excel to calculate the average value of the waveform's frequency, average value of the serial monitor's frequency, the difference between waveform's frequency and serial monitor's frequency and the percentage error of the differences between both value.

2. Soldering New Sound Sensor

📌 Due to the microphone of the sound sensor is broken, the microphone is soldered back to the sensor but it still cannot be used. Thus, a new FC-04 sound sensor module is bought and soldered to complete the hardware of the project. So, the collection of data can be continued done.

Activities :

1. Eighth meeting with FYP2 Supervisor - Sir Shah Rizailli Mukhtar

📆 23 October 2019
⌚ 10.00 am - 12.15 pm
📬 SPS 209, Level 2

📌 Supervisor asked to see the progress of the project. The prototype is shown to the supervisor and how it works for battery failure and NIBP cuff failure.

📌 During the testing of the prototype, supervisor did some hard loud sound which indicates the construction sound in real life to see if the prototype able to avoid capturing those noise or not. Even though the prototype is good enough because it capable to avoid the noises that supervisor has created, yet it still needs to improvise in the coding section due to during the battery failure, sometimes the output in Telegram is NIBP cuff failure instead of battery failure. The coding must improvise by putting the range of frequency more specific.

📌 Supervisor also asked to improve in the collection of data by matching the data from the serial monitor of Arduino IDE software with the data from the oscilloscope to observe the accuracy of the results.

2. Literature review

📌 Another problem with the coding of the prototype is because the coding does not have any delay. Thus, when the prototype captured the alarm, the output will be sent to the Telegram repetitively. 1ms 1 notification and this situation kind of irritating because the notification will still notify in the smartphone even though the alarm has been turned off. It is advisable to get at least 1 notification for 5 seconds of the alarm.

📌 This situation maybe can be avoided by using the delay function in the coding but the problem with delay function is it will delay the program instead of only give 1 notification for 5 seconds because delay function only pauses the program flow.

📌 Instead of using delay function, millis() function is preferable to configure this problem because millis() function returns the amount of milliseconds that have passed since the program start. It also would not prevent running the coding while waiting the data to be processed. It is better to use this function for sampling instead of using the delay function.

📌 More information can be read here >> Using millis() instead of delay()

Activities :

1. Suggestion on improvements

📌 Instead of using two 9V batteries for supply, the prototype can use one 9V battery supply with the implementation of a voltage divider circuit.

📌 Instead of use 9V batteries which are bigger in size, it is advisable to use 5V coin battery to save space.
📌 Improvement in the collection of data can be done by collecting more data to make it more accurate.

📌 The collection of data is also advisable to use various technique such as using LabView software instead of only using the oscilloscope.

📌 The whole connection of the Arduino NANO board, NodeMCU board, signal conditioning circuit and sound sensor can be further improvised to make it smaller in size by desoldering all the unused pins of Arduino NANO board and NodeMCU board and stack up all together.

2. Technical Paper - draft

📌 Technical paper is a document that describes the process, progress, state of technical problem or in a simple wording is a summary of the full report of the prototype. It is advisable to be written for 4 to 5 pages. Technical paper contains abstract, introduction, methodology, result, discussion, conclusion and references. It might also include recommendations and conclusions of the project.

Activities :

1. Designing FYP2 banner and casing for the prototype.

📆 6 October 2019

📌For the FYP2 Exhibition day, every FYP2 student must present by using a banner and demonstrate the prototype. For the banner, I designed it using Adobe Photoshop CS4 software because it is much easier to adjust the size of the banner in the software. The banner is printed at Achik Printing Taman Melawati Sdn Bhd.

The layout of the banner with size (2 x 6 ft).

📌 Basically, this project is successful by giving supply from two 9V batteries for Arduino NANO board and NodeMCU board respectively. This prototype may become more effective if there is a presence of switch to on and off the prototype.

📌 The video of the layout can be seen here >> Video of prototype layout.

3. Testing with the presence of a switch

📆 8 October 2019

📌 After being considered to put a switch to make it more effective, I have soldered the batteries with the switch but due to the batteries are new battery, so the current flow is too high and it makes the NodeMCU became faulty and cannot be used. I tried uploading the coding into the NodeMCU but the code cannot be uploaded into it. I try to connect the circuit with my friend's NodeMCU board and the data can be transmitted successfully. Thus, a new NodeMCU board is bought from the Autobotic Sdn Bhd shop.

The switch is connected based on this sketching.

📌 After the NodeMCU is bought, the whole circuit is constructed back all together and the prototype works but without the switch. A video is taken as proof for the FYP2 exhibition day. Supervisor said to connect a switch must put a voltage regulator so that the current flow is low.

📌 The video of the final output can be seen here >> FYP2 prototype

📌 After the video is taken, I tried to solder the new NodeMCU together with the circuit but it failed. The data does not transmit to the Telegram. The serial monitor also does not print any output. After several troubleshoot, the pin of Tx Rx of the Arduino NANO board cannot be used. That is why the NodeMCU board does not receive any data from Arduino NANO board.

4. Troubleshoot prototype.

📆 9 October 2019

⌚ 7.45 am to 8.30 am

📬 Research Lab, Level 4, UniKL BMI

📌 Due to the Tx Rx pin of the Arduino NANO board are faulty, so it is replaced by a new Arduino NANO board and been soldered again the whole circuit and put it in the casing. The whole prototype can function well and is prepared to be demonstrated on FYP2 Exhibition Day at 9.00 am on the same day.

5. FYP2 Exhibition Day

📆 9 October 2019

⌚ 9.00 am to 2.00 pm

📬 Gemilang Hall, UniKL BMI

📌 For FYP2 Exhibition Day, there are two parts of presentation which are demonstration of the project and the presentation of the technical part.
📌 There are two assessors; Madam Siti Afifah binti Mohshim (UniKL BMI's lecturer) and Mr. Syukran Che Pa (Sales & Services Engineer of EASMED Sdn Bhd).
📌 The recommendation from Mr. Syukran Che Pa are the device can be smaller by desolder all the unused pin on Arduino NANO board and the NodeMCU board and by put voltage divider circuit so that the supply only needs to use one battery instead of two. But he said, if this prototype is used for imaging equipment, it is breaking the ACT 737 law because it involves the Wi-Fi networking.

Week : 10
Date : 29 Sept 2019 - 5 Oct 2019

Activities :

1. Coding - TelegramBot

📆 30 September 2019

📌 For this project, the final output must be sent to the end-users social media specifically to the Telegram application. Telegram is cloud-based storage, so end-users do not need to back up or restore the data receives and send. I am having a problem with the coding which is the Arduino WeMos board cannot transmit the data received from Arduino UNO board to the Telegram via Wi-Fi connection. Arduino WeMos only succeed to connect to the Wi-Fi network but not transmitting any data to the Telegram.

📌 I only managed to create a TelegramBot for the project which is named alarmpmBot. This bot is created using BotFather in the Telegram application. BotFather gives the token of the alarmpmBot to access the HTTP API. By declaring this token in the coding, Arduino WeMos can transmit the data directly to the Telegram.
📌 Unfortunately, Telegram still cannot be connected to the Arduino WeMos board and this problem needs to be troubleshoot.

2. Improvement Advice by Supervisor.

📆 1 October 2019

📌 Due to the signal conditioning circuit is a bit bigger, supervisor asked to desolder it back and construct it into a much compact circuit and if possible the same size of 50 cent. Even though the circuit is the same size as the Arduino UNO board and Arduino WeMos board, the advice by supervisor is being considered.

3. Desoldering signal conditioning circuit

📆 2 October 2019

⌚ 2.00 pm to 3.00 pm

📬 Research Lab, Level 4, UniKL BMI

📌 After being considered with the advice by supervisor, the signal conditioning circuit is desoldered and soldered back with a new circuit which is more smaller and compact. Even though it is a little bit bigger than 50 cents, but it is much compact and better than the previous one.
📌 A technician who in charge of the research lab in Level 4 suggested to use Arduino NANO board instead of Arduino UNO board and NodeMCU board instead of Arduino WeMos board. The suggestion is made because the project if possible is develop as small as possible. The suggestion is being considered.

5. Final Year Project 2 Workshop

📆 2 October 2019

⌚ 3.00 pm to 5.00 pm

📬 TTL 2

📌 Speaker : Dr Imran Mohd Sofi
📌 Workshop on FYP2 Exhibition Day (Tips & Tricks) and submission of progress report, final report and technical paper.
📌 Submission date for the progress report, final report and technical paper : 29 November 2019

6. Buy components for the development of hardware.

📆 3 October 2019

📬 Autobotic Sdn Bhd, 4th floor, Jalan Semarak Api 3

📌 After being considered with the suggestion by the technician and further reading of the component datasheet, the Arduino NANO board and NodeMcu board were bought from the Autobotic Sdn Bhd.
📌 Arduino NANO board is a small, complete, breadboard-friendly board compare to the Arduino UNO board which is much bigger in size. Even though the Arduino UNO board can use to do lots of things due to its input and output pin is more compared to the Arduino NANO board but because the sound sensor only required one analog pin, it is better to use Arduino NANO board to save space. Arduino NANO board can also be programmed in it and the hardware will be simpler easier to bring everywhere. This is convenient for this project as the prototype needs to be as tiny as possible and the Arduino NANO board is the cheapest Arduino board option available making it cost-effective for this project.
📌 NodeMCU board is the best ESP platform available if look from the hardware perspective. NodeMCU can be programmed the same as the Arduino board and it can stand alone. It is used as Wi-Fi module in this project. Even though Arduino WeMos board has the same function as NodeMCU board but due to it has bigger dimension, NodeMCU is much more convenient to be used.

7. Coding - TelegramBot

📆 5 October 2019

📌 This coding is actually the continuing of the previous TelegramBot coding. The previous problem is because the Telegram still cannot be connected to the Arduino WeMos board.

📌 After being troubleshooting for several days, the problem with the coding is because the library of Arduino JSON that been installed is version 6.12.0. This version is the latest of Arduino JSON thus, it is still not stable and not compatible with the Telegram. That is why Arduino WeMos cannot connect to the Telegram via the Wi-Fi network. After downgraded the version Arduino JSON from 6.12.0 to 5.13.4, Arduino WeMos successfully transmit the data from Arduino UNO board to the Telegram via Wi-Fi connection.

Arduino JSON version 5.13.4

Telegram alarmpmBot notification on battery failure and NIBP cuff failure

*click to expand image*

📌 Due to the hardware is advised to be as small as possible, the coding for interpreting data is uploaded in the Arduino NANO board as a replacement for the Arduino UNO board meanwhile the coding for TelegramBot is uploaded into the NodeMCU as a replacement for the Arduino WeMos board. At first, I want to use only NodeMCU to function as the interpreter data and the receiver and transmitter of the output because NodeMCU can stand alone with the Arduino program but because of NodeMCU cannot read interrupt function, the prototype must use Arduino NANO board and NodeMCU together to make it function well.
