Servos have stopped responding - help me out?

Hi everyone! First time posting on here, so tell me if I've made a mistake in the way I posted.

I've been making this robotic arm with multiple servos on top of an obstacle-avoiding rover, and a few days ago the codes for the arm stopped working properly. I thought, y'know, must be power or something, so I charged my LiPos until the charger showed they were alright and tested them out again today. Again, they worked alright for a few minutes before they just randomly stopped.

I've been testing them out with a Sweep code, and reading servo position tells me they're moving, but it's not physically moving, so I don't know.

#include <Servo.h>

Servo myservo; 
Servo myservo2;
Servo myservo3;// create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {
  Serial.begin(115200);
  //myservo.attach(42);
  //myservo2.attach(41);
  myservo3.attach(44);// attaches the servo on pin 9 to the servo object
}

void loop() {
  //myservo.write(20);
  //delay(250);
  //myservo2.write(0);
  //delay(250);
  for(int i = 0; i <= 180; i++){
    myservo3.write(i);
    delay(15);
    Serial.println(myservo3.read());
  }
  for(int i = 180; i >= 0; i--){
  myservo3.write(i);
  delay(15);
  Serial.println(myservo3.read());
}

That's the code I've been trying out with. I have a separate power for all these Servos, and I've connected the GND of the battery with the GND of the servos and of the Arduino through breadboard. I'm operating an Arduino MEGA, any help or advice anyone? I can't see what I'm doing wrong.

No, it merely tells you the value you wrote last.

3

Post images of your project.

Are you using one of these?

Servo issues are most often a lack of power. It sounds so in your case too. It's not clear how your power is connected - going through a breadboard would not be good - they can't manage much current.

The Servo read() function reference.

You need to show your circuit AND what battery AND what servos.
Many servos are only rated to 6v maximum.
