## 5. Memo / Trial & Error

- Set to ESP32 Dev Module in IDE.

- Button on right side of the microusb port should be pressed when uploading code. Press the other button to reboot after uploading.

- You should set COM port as "send" on the device when you connect to ESP32 (Windows).

- Quit openFrameworks app (ofApp) that gets serial data before uploading data to ESP32.

- Haptic feedback of LilyPad Vibe Board feels a little bit weak on wrist. But still stronger than Qwiic Haptic Driver DA7280.
