The SG90 Micro Servo Motor is a compact and lightweight servo designed for projects that require precise angular movement. With a 180-degree rotation range, it's the go-to choice for Arduino, robotics, and automation hobbyists.

Whether you're building a robotic arm, a smart lock, or a pan-tilt mechanism, the SG90 offers reliable performance with easy setup.

🔧 Key Features:

• Rotation Range: 0° to 180°

• Operating Voltage: 4.8V–6V

• Stall Torque: 1.8kg/cm (at 4.8V)

• Weight: ~9g

• Control Signal: PWM

• Includes: 3 servo horns and mounting screws

🔌 Wiring Guide (Arduino UNO):

• Orange (Signal) → Pin 9 on Arduino

• Red (VCC) → 5V

• Brown (GND) → GND

💻 Library & Code Example:

You’ll need the built-in Servo.h library (no extra installation required).

#include <Servo.h>

Servo myServo;  // Create servo object

void setup() {
  myServo.attach(9);  // Attach to pin 9
}

void loop() {
  myServo.write(0);    // Move to 0°
  delay(1000);
  myServo.write(90);   // Move to 90°
  delay(1000);
  myServo.write(180);  // Move to 180°
  delay(1000);
}
