This week, I focused on sourcing and researching components needed for the LED strip circuitry. Specifically, we required a signal and power booster to meet the 5V requirement of the LED strips while operating on a 3.3V system. Although I had planned to begin LED integration, our ESP32 was confiscated by TSA at an airport, preventing direct testing. In the meantime, I wrote and prepared code in the Arduino IDE to facilitate testing once we receive a replacement next week.
The project remains on schedule. For the upcoming demo, we plan to integrate the LED system with NFC scanners and tags. 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.
Next week, I aim to finalize the LED setup by cutting the strips into four sections, each corresponding to a specific zone of the pad. The goal is to enable the LEDs to change colors—green, yellow, or red—based on backend notifications.
