servomotor (arduino)

Hello, I am looking for a program to monitor 4 servomotors by a detector ultrasonic HC-SR04 (external power supply). The movement of each servo is different.
I am totally beginner.

Thank you to all

9V will be too high for the servos probably so unless you have a DC-DC converter or a 5V regulator it may be better to go with the 4*1.5V batteries

I think the code was accidentally pasted twice, delete the second copy of the declarations, Setup() and Loop() methods etc then it should work
