The recently assembled servos have not been set to their home positions. Since the servos used in this case are the most affordable ones, their encoder accuracy is not high. Achieving precise angle control may be challenging. However, we can compensate for the lack of accuracy by defining the maximum, center, and minimum positions and mapping the positions in between relatively.

The video shows the servos adjusted to their maximum angle positions. The angles of each pixel appear to be almost consistent.

I have completed the calibration of the device, so I tried coding the wave motion.
