PCA9685 Debugging Panel

This is a web-based remote-control panel for debugging PCA9685 servo drivers on robots.
The first problem I encountered was the accessibility of the hardware. Sometimes I want to debug the UI and API, but I don't have a PCA9685 board nearby. So, I co-op with Deepseek to develop the mock mode, enabling the robot to "pretend that it has established an I2C connection to a PCA9685 driver".
If you are using the PCA9685 on your robot, you can easily debug it by simply installing this package via pip on the robot. Even if you don't have the corresponding hardware, you can also use the mock mode to observe how the UI works. I hope this will inspire you.
I'm still working on this project, and I hope it to become a "de facto standard" sometime.
