This week I continued working on the other three folding fans and the interactive interface for the gesture sensor.

There are 3 iterations when I design the interactive interface. (I forget to take photos of it…)

1st version:  The hole is too small, and the sensor can NOT detect ANY actions.

2ed version: The gesture sensor can detect actions for this version, but since the narrow height of the new hole, it’s easy for the sensor to detect the WRONG gesture.

3rd version: The sensor works well at this time. The hole should be big enough to ensure the interface’s appearance, so I make a fan-shaped hole.

🤔️ Questions:

When I tested it, I found that 5 fans can open and close smoothly about 3 times later, it will be like a power failure. The serial monitor shows the sensor also did not have any response. After reconnecting the Arduino or re-uploading the code, it will resume. I guess it’s because of the motor?? Because I have checked the code and power supply, there should be no problem.
