• Speed: 0.1s/60° (4.8V), 0.09s/60° (6V)
• Rotation Angle: 0° to 180°
• Connector Type: 3-wire (Signal, Vcc, Ground)

Features

• Compact and lightweight design.
• High efficiency and low power consumption.
• Wide compatibility with Arduino, Raspberry Pi, and other microcontrollers.
• Durable plastic gear for smooth operation.

Applications

• Robotics: Small robotic arms and grippers.
• RC Vehicles: Steering mechanisms.
• Cameras: Pan-and-tilt mechanisms for lightweight cameras.

How to Use SG90

To control the SG90 with Arduino:

1. Connect the SG90's signal wire to a PWM pin on the Arduino.
2. Provide power (5V) and ground connections.
3. Upload the following code:

#include 
Servo sg90;

void setup() {
  sg90.attach(9); // Connect to pin 9
}

void loop() {
  sg90.write(0);   // Rotate to 0°
  delay(1000);
  sg90.write(90);  // Rotate to 90°
  delay(1000);
  sg90.write(180); // Rotate to 180°
  delay(1000);
}
