I made the project on the basis of Android platform that is Free Open Source Software.
CE 2.3.4 Identified issues and their solutions
2.3.4.1 Issues
The most important concern that I have confronted in this project was during selecting the Bluetooth module. I had previously selected the version of ESP8266 Arduino compatible serial ESP-01. This was providing erroneous results to this project and the door locking system was not working properly. The second issue that I had faced here was setting the rate of data transmission. I had selected the data rate of 8000 kbps and hence got the result that was not expected in this project. These issues were bringing major delays in the project.
2.3.4.2 Solutions
For the first problem of selection of Bluetooth module, I gave the solution of HC- 05 version. Since, this module was easier to use the Bluetooth SPP or Serial Port Protocol for designing the transparent wireless serial connection setup. I easily connected this module with V2.0+EDR at 3mbps. For the next issue, I understood that higher data rate transmission would be required in the project and thus gave the idea of using 9600kbps. These solutions helped in resolving the issues properly.
CE 2.3.5 Plan to produce creative and innovative work
To execute this particular project of Designing of Automated Door Locking System, I had to make a distinct plan for producing excellent designs as well as works. Being one of the electronics engineer by profession, it was my core duty to make the design for this door locking system with appropriate efficiency and accurateness.
CE 2.3.6 Collaborative Work
I provided suggestions to my team for working altogether for the reason that it becomes stress-free for each of us to make the project successful. I then distributed the various tasks equally within my other members of the team and undertook daily work follow ups.
CE 2.4 Project Review
CE 2.4.1 Project Overview
The key purpose of this project was proposing a suitable design for automated door locking system. For this particular purpose, I had to use my information of Bluetooth module of HC-05 as well as microcontroller technology of ATmega16 to integrate the design.
CE 2.4.2 My Contribution to work
I was assigned as the chief electronics engineer in this detailed project of Designing of Automated Door Locking System. My chief contribution was proposing the accurate design for this project and also solving the several issues faced by us.
