This week was doing tests on our breadboard version that we presented demo videos of in our presentation. We did a bunch of tests to verify that the communication between the ESP and phone worked as well as sending messages either from the phone or from cellular itself. We expected the results to be no more than 15 seconds and all the tests passed. Regarding other tests like battery life and RFID/mic, we weren’t able to do due to the PCB not working yet and and finishing up RFID and the mic.
Anika debugged the PCB this week to figure out what was wrong and if this was an issue that can be solved or if the PCB won’t be able to work in time. The voltage regulators were not working when we powered the board and the lithium ion battery would die every time we plugged it into the board. Because all the components worked when put tested on the breadboard, it was deemed be an issue with the board itself. At this time, because we are so close o the demo we can’t redo our PCB and need to focus on finishing implementing everything on the breadboard, which we have begun this week. We seem to be able to fit all the components onto a very small breadboard, and we will use this to represent our pendant. We also found a new battery component we can use instead of the lithium ion battery that was much smaller than the previous one.
