Servo Motors are vibrating

[jfsc]

Hi, I'm new to arduino and I'm having some hardware problems.

I was working normally with my robot and I raised my last setting and out of nowhere the servos started vibrating too crazy, any opinion is welcome...

Here is the code:
`#include <Servo.h>

int ServoPin1 = 9;
int ServoPin2 = 5;
int ServoPin3 = 6;
int ServoPin4 = 10;
int Correr4_A = 63;
int Correr3_A = 117;
int Correr4_B = 60;
int Correr3_B = 120;
int CaminarDE_A = 130; // Caminar derecho
int CaminarIZ_A = 40; // Caminar izquierdo
int CaminarDE_B = 40; // Caminar derecho
int CaminarIZ_B = 130; // Caminar izquierdo
int Central = 90;
int Gateo_24 = 60;
int Gateo_13 = 110;
int PataDD = 100;
int PataDI = 80;
int Tiempo_Co = 800;
int Tiempo_Ca = 1000;
int PinSensor = 2;
int EstadoSen = 0;
Servo Servo1; // Delantero Derecho
Servo Servo2; // Delantero Izquierdo
Servo Servo3; // Trasero Derecho
Servo Servo4; // Trasero Izquierdo

unsigned long tiempoInicio = 0; // Variable para guardar el tiempo cuando se toca el sensor
unsigned long tiempoDuracion = 0; // Variable para calcular el tiempo transcurrido

void setup() {
// Configuración de los servos
Servo1.attach(ServoPin1);
Servo2.attach(ServoPin2);
Servo3.attach(ServoPin3);
Servo4.attach(ServoPin4);

// Posición inicial de los servos
Servo1.write(PataDD);
Servo2.write(PataDI);
Servo3.write(90);
Servo4.write(90);
delay(10000);

pinMode(PinSensor, INPUT); // Configurar el pin del sensor como entrada
}

void loop() {
// Función para caminar

/*Servo1.write(CaminarDE_A);
Servo2.write(CaminarIZ_A);
Servo3.write(CaminarDE_A);
Servo4.write(CaminarIZ_A);
delay(Tiempo_Ca); // Pausa de 1 segundo

Servo1.write(CaminarDE_B);
Servo2.write(CaminarIZ_B);
Servo3.write(CaminarDE_B);
Servo4.write(CaminarIZ_B);
delay(Tiempo_Ca); // Pausa de 1 segundo
*/

// Función para correr

Servo1.write(90);
Servo2.write(90);
Servo3.write(Correr3_A);
Servo4.write(Correr4_A);
delay(Tiempo_Co);
Servo1.write(120);
Servo2.write(60);
Servo3.write(Correr3_B);
Servo4.write(Correr4_B);
delay(Tiempo_Co);

// Función para gatear

/*Servo1.write(Central);
Servo2.write(Gateo_24);
Servo3.write(Gateo_13-10);
Servo4.write(Central);
delay(Tiempo_Ca);

// Gateo
Servo1.write(Gateo_13);
Servo2.write(Central);
Servo3.write(Central);
Servo4.write(Gateo_24+10);
delay(Tiempo_Ca);*/
}
` Very thank you.

Vibrating servos is almost always due to a power problem.

So which servos, and how are you powering the servos.

• Always show us a good schematic of your proposed circuit.
  Show us good images of your ‘actual’ wiring.
  Give links to components.

I´m using MG90s servo motor and I am using a power card for protoboard it I giv power with an adapter of 9V.

[LarryD]

@jfsc

MG90s

• These servos require an operating voltage: 4.8 V - 6.0 V.
  9 volts is too high.

• What are the specifications of the power supply are you using ?

[jfsc]

No, my power card out is of 5 volts

[Wawa]

The adapter must be rated for 2.5Amp or more for those four MG90 servos.

Do you also power the Arduino from that adapter?
Leo..

[jremington]

The servo power supply is inadequate. Use a separate supply capable of providing at least 3 Amperes at 4.8 to 6V, and don't forget to connect the grounds.

Very thank you!!! I think that was the amper of my input.
