Steps
- Decide where the IMUs sit on the back and define what good and bad posture look like.
- Wire the IMUs, vibration motor, buzzer, and SD card module to the ESP32.
- Program the ESP32 to calculate posture angles and log them.
- Add a vibration alert when posture stays bad for more than a few seconds.
- Wear it for several days and track how often alerts fire over time.
- Chart posture improvement and document the device for your portfolio.
What to photograph for your portfolio
