Arduino side:

Code:

void setup() {
  Serial.begin(9600); // Start serial communication at 9600 baud
  for (int i = 0; i < numServos; i++) {
    servos[i].attach(servoPins[i]); // Attach each servo to its pin
  }
}

void loop() {
  static int servoIndex = -1; // Static variable to keep track of the servo index
  if (Serial.available() > 0) {
    int value = Serial.parseInt(); // Read the next integer from the serial buffer
    if (servoIndex == -1) {
      // If servoIndex is -1, this value is the servo index
      servoIndex = value;
    } else {
      // Otherwise, this value is the servo position
      int servoPosition = value;
      if (servoIndex >= 0 && servoIndex < numServos) {
        servos[servoIndex].write(servoPosition); // Move the specified servo to the position
        Serial.print("Servo ");
        Serial.print(servoIndex);
        Serial.print(" moved to ");
        Serial.println(servoPosition);
      }
      servoIndex = -1; // Reset servoIndex for the next command
    }
  }
}


computer side(Python):

Code:

import serial
import time

# Replace 'COM3' with the appropriate port for your system
ser = serial.Serial('COM3', 9600)
time.sleep(2)  # Wait for the serial connection to initialize

def send_servo_command(servo_index, servo_position):
    command = f"{servo_index} {servo_position}\n"
    ser.write(command.encode())
    print(f"Sent command: {command.strip()}")

# Example usage
send_servo_command(0, 90)  # Move servo 0 to 90 degrees
send_servo_command(1, 45)  # Move servo 1 to 45 degrees

ser.close()
