Description
The SG90 Micro Servo is a small and versatile servo motor ideal for use in robotics, model making, and other precision control applications. This servo offers 180-degree rotation with a torque rating of 1.8 kg.cm, making it suitable for tasks that require light to medium load control. It features durable plastic gears and operates with a standard PWM signal for position control.
Key Features:
- Rotation: 0 to 180 degrees
- Torque: 1.8 kg.cm (at 4.8V)
- Power Supply: Typically operates at 4.8V to 6V
- Control Signal: Standard Pulse Width Modulation (PWM)
- Gear Material: Plastic (lightweight and cost-effective)
- Weight: Approximately 9g (lightweight)
- Dimensions: 22.5 x 11.5 x 29mm (compact size)
- Current Draw: Around 500mA (under load)
Applications:
- Robotics: Used for controlling limbs, grippers, and other movements.
- Modeling: Ideal for RC cars, airplanes, or boats for steering and throttle control.
- Educational Projects: Great for beginners learning about servos and motor control.
- Automation: Can be used for opening/closing doors, adjusting angles, or controlling small robotic arms.
Benefits:
- Compact and Lightweight: Ideal for small-scale projects and applications with space constraints.
- Affordable: Provides a cost-effective solution for lightweight, precise movements in hobby and DIY electronics.
- Easy to Use: Simple to integrate with Arduino, Raspberry Pi, or other microcontroller-based systems using PWM control.
The SG90 Micro Servo is an excellent choice for low-torque, precise positioning tasks in electronics projects, robotics, and hobby applications.

Code Comments:
The servo moves between 0 → 90 → 180 degrees.
If the servo is shaking or unstable:
May be needed to Use an external 5V power supply.
Connect a common GND between the Arduino and the power supply.
