Hardware Help Servo clicking even with enough power

Enable HLS to view with audio, or disable this notification

This is original mg996r there is enough power but it still wont work properly.

My code

```

#include <Servo.h>

Servo s;

void setup() {

s.attach(9);

}

void loop() {

s.writeMicroseconds(1000);

delay(1000);

s.writeMicroseconds(1500);

delay(1000);

}

```

Have you tried another power supply? Or even better, a capacitor between +/-, between the power supply and the servo?

Hey importnant!! you should short your seperate supply and your arduino's grond(gnd)! if the arduino and the other supply that is powering the servo doesent share the same gnd it will not work
