Memo / Trial \u0026 Error\n- Set to ESP32 Dev Module in IDE.\n- Button on right side of the microusb port should be pressed when uploading code. Press the other button to reboot after uploading.\n- You should set COM port as \"send\" on the device when you connect to ESP32 (Windows).\n- Quit openFrameworks app (ofApp) that gets serial data before uploading data to ESP32.\n- Haptic feedback of LilyPad Vibe Board feels a little bit weak on wrist. But still stronger than Qwiic Haptic Driver DA7280.\n- [Qwiic 6DoF Gyro/Acc LSM6DSO library](https://learn.sparkfun.com/tutorials/qwiic-6dof-lsm6dso-breakout-hookup-guide) and [Qwiic Haptic Driver DA7280 library](https://learn.sparkfun.com/tutorials/qwiic-haptic-driver-da7280-hookup-guide?_ga=2.22013947.1502922294.1671452785-154993728.1671452785) crashes on arduino ide\n## Acknowledgement\nThe project [Sunny Day](https://ssk7808.github.io/sunnyday/) was funded by [National Research Foundation Korea](https://www.nrf.re.kr/eng/index) as University Innovation program, 2022\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchanulee%2Falpha","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fchanulee%2Falpha","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchanulee%2Falpha/lists"}
