Code to Note:
In the previous assembly, we have set the square wave and servo angle. So we should use the servo libraries to
control the angle of each servo. The test result is the same. Before using, place the Servo folder inside the libraries
folder of Arduino IDE directory, then open the Arduino IDE, and the libraries are able to use.
You can download all the libraries for test code from the link:
