The most significant challenge we encountered this week was our esp32 microcontroller being taken away by TSA at the airport. This meant that our testing and integration process was delayed, and we had to borrow other microcontrollers to test with. We mitigated these risks by quickly ordering more esp32s and picking them up this week. We will be using these to implement and test our NFC scanning and other sensors for upcoming demos.
While connecting the NFC physical scanner to our esp32, the microcontroller was not able to detect the scanner so we suspect that the scanner must also be powered by 5V instead of 3.3V. In order to account for this, we are going to use the power booster (which has been ordered) on the NFC scanner as well.
No significant updates to the schedule have been made, we were able to overcome our loss of esp32 by quickly ordering another one and borrowing others. For the upcoming demo, we plan to integrate the LED system with NFC scanners and tags with our current prototype. This will allow the system to correctly recognize stickers on objects placed in different zones of the pad and send real-time notifications to the frontend.
