This week, I spent a lot of time working on our final presentation as well as adding some minor changes to the web application backend. For our presentation, I help set up the initial outline, worked on the complete solution slides, added to the design trade-offs slide, and added tests related to my portion of the project to the testing, verification, and validation slides. Additionally, I performed some tests on our RPi to web server connection by timing how long it took for a scan and its data to be sent to the web server backend. This time was always under 2 seconds (which was our goal), and the average time was 0.96 seconds. In addition to the presentation, I was also able to set up our web application to be encrypted with SSL. This required getting a domain name and obtaining the certificate so that our traffic could always be rerouted to https. By visiting https://waitr.link, you can view our web app running encrypted through our EC2 instance! I also added some logic to have both the live wait time to be viewed alongside the predicted wait time on the web app frontend.
My progress is currently on schedule. Next week, I hope to help out with our final poster as well as finish getting the Arduino and RPi connected so that our project solution can finally be complete. I also want to make sure that there is nothing else needed on the web app backend before the final demo.
