The components we had been waiting on finally arrived, and we collected the full set later in the week, turning a paper architecture into something we could actually hold. With the parts in hand, we wrote the first ESP32 test code, the firmware that reads each sensor and confirms the electronics behave the way we expected. We also gathered a fresh round of feedback on our concept during a conversation with the speaker from Sword Health at SINFO, a welcome outside perspective at exactly the right moment. On the software side, the first working version of our mobile application came together, giving the cognitive tasks a real place to live.
