Ive run out of pins to control servos

ive been using 2 libraries servo.h and IRremote.h, that aparently disable PMW on some pins? im not sure, but i cant seem to use pins 10-13 to control servos

#include <Servo.h>
#define IR_USE_AVR_TIMER 2
#include <IRremote.hpp>

const int recv_pin = 2;
const int motor1pin1 = 3;
const int motor1pin2 = 4;
const int motor1pinENA = 5;
const int motor2pin1 = 7;
const int motor2pin2 = 8;
const int motor2pinENA = 6;
const int pinServoGripper = 9;
const int pinServoTangan = 10;  //this is the servo that wont work!!!!!!

Servo Tangan;
Servo Gripper;

void setup() {
  IrReceiver.begin(recv_pin);
  Serial.begin(9600);
  Gripper.attach(pinServoGripper);
  Tangan.attach(pinServoGripper);

  pinMode(pinServoGripper, OUTPUT);
  pinMode(pinServoTangan, OUTPUT);
  pinMode(recv_pin, INPUT);
  pinMode(motor1pin1, OUTPUT);
  pinMode(motor1pin2, OUTPUT);
  pinMode(motor1pinENA, OUTPUT);
  pinMode(motor2pin1, OUTPUT);
  pinMode(motor2pin2, OUTPUT);
  pinMode(motor2pinENA, OUTPUT);

  Gripper.write(30);
  Tangan.write(140);
}

void loop() {
  // put your main code here, to run repeatedly:
  if(IrReceiver.decode())
  { 
    Serial.println(IrReceiver.decodedIRData.decodedRawData , HEX);
    
     switch(IrReceiver.decodedIRData.decodedRawData)
     {

sorry, the code is written in indonesian, its for a contest

The IR library uses a timer which is also used for PWM. So yes you can’t use all pins.

See this Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface [PCA9685] : ID 815 : $14.95 : Adafruit Industries, Unique & fun DIY electronics and kits to drive your servos with an extra component

Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs

is there really no way to control the servo with any other pin? maybe with an analog pin or the digital pins 1 and 0?

You need PWM to drive the servo. There are software emulations for PWM like GitHub - adafruit/Adafruit_SoftServo: A lightweight software servo library, designed for Trinket/Gemma but good for other Arduino-compats

May be you’ll find one that works for your set up.

My recommendation would be to use appropriate hardware (a mega or port extension with PWM)

The Servo.h doesn't need PWM capable pins. It creates the servo pulses per software in a timer interrupt. So it should work on all digital pins.

But you attached the same pin to both servos and never used pinServoTangan :

N.B:

You don't need to set the servo pins to OUTPUT. This is done by the servo lib.
