5. Setup

Follow these steps to set up your MG90S Micro Servo:

1. Connect the Servo: The servo has three wires: brown (Ground), red (VCC/Power), and orange/yellow (Signal). Connect these to your control board (e.g., Arduino) according to its pinout.
2. Attach Servo Arm: Select the appropriate servo arm for your application from the included accessories. Secure it to the servo's output shaft using the provided small screw.
3. Mount the Servo: Use the mounting screws and any necessary brackets or vibration dampers to securely attach the servo to your project. Ensure it is firmly in place to prevent movement during operation.
4. Power Supply: Ensure your power supply provides the correct voltage (4.8V) and sufficient current for the servo.

6. Operating Instructions

The MG90S Micro Servo is controlled using Pulse Width Modulation (PWM) signals. The pulse width determines the angle of the servo arm.

1. PWM Signal: A typical servo expects a pulse every 20ms (50Hz). The duration of this pulse dictates the servo's position.
2. Angle Control:
   • 0° Position: Achieved with a pulse width of approximately 0.5ms.
   • 90° (Neutral) Position: Achieved with a pulse width of approximately 1.5ms.
   • 180° Position: Achieved with a pulse width of approximately 2.5ms.
3. Programming: For microcontrollers like Arduino, use the Servo library to easily control the servo's angle. For example, `servo.write(angle)` where 'angle' is between 0 and 180 degrees.
4. Applications: These servos are commonly used in RC vehicles (helicopters, cars, boats), robotic arms, and various Arduino-based projects requiring precise angular movement.

7. Maintenance

To ensure the longevity and optimal performance of your MG90S Micro Servos, consider the following maintenance tips:

• Keep Clean: Regularly clean the servo's exterior to prevent dust and debris from entering the mechanism.
• Avoid Overloading: Do not apply excessive force or torque beyond the servo's rated specifications, as this can damage the gears or motor.
• Check Connections: Periodically inspect all wiring and connections for looseness or damage. Secure any loose connections.
• Storage: Store servos in a dry, cool environment away from direct sunlight and extreme temperatures.

8. Troubleshooting

If you encounter issues with your MG90S Micro Servo, refer to the following troubleshooting guide:

• Servo Not Moving:
  • Check power supply: Ensure it provides adequate voltage and current.
  • Verify wiring: Confirm that the Ground, VCC, and Signal wires are correctly connected.
  • Check control signal: Ensure your microcontroller is sending the correct PWM signal.
• Inaccurate or Erratic Movement:
  • Review code: Ensure your programming logic for angle control is correct.
  • Check for mechanical obstruction: Ensure the servo arm or connected mechanism is not binding or obstructed.
  • Power supply fluctuations: Unstable power can cause erratic behavior. Use a stable power source.
• Excessive Noise:
  • Normal operation: Metal gear servos can be slightly noisier than plastic gear servos.
  • Overload: If the servo is straining, it may produce excessive noise. Reduce the load or check for obstructions.

9. Safety Information

Please observe the following safety precautions when using the MG90S Micro Servo Motor Kit:

• Electrical Safety: Always ensure correct wiring and power supply voltage to prevent damage to the servo or control board.
• Moving Parts: Keep fingers and other objects clear of moving servo arms to avoid injury.
• Age Recommendation: This product is recommended for users aged 8 years and up. Adult supervision is advised for younger users.
• Environmental Conditions: Do not expose the servo to extreme temperatures, moisture, or corrosive environments.
