and after webServer.py is running, it will control all the servo ports to send signals to
move to the middle position. When you install the servo rocker arm, you can connect
the servo to any port at any time. When the servo is connected to the port, the servo
will rotate to the middle position. Install the rocker arm according to the specified
angle then you can disconnect the servo from the port and plug in a new servo that has

rotate to the middle position.
4. It takes a while to boot the Raspberry Pi to control the PCA9685 to set all the
servo ports to the signal to rotate to the middle position. The boot process of the
Raspberry Pi is about 30-50s.
5. All the servo rocker arm installation angles shown in the document are the
