SG 90 Tower Pro Micro Servo Motor

Question 1.

How is the SG90 servo motor controlled?

How is the SG90 Servo Motor Controlled?

The SG90 servo motor operates using a system called Pulse Width Modulation (PWM), which is a popular method for managing the position of the servo.

Components and Connections

To control the SG90, you'll need to connect its three main wires:

1. Power - Supplies the necessary voltage to the motor.

2. Ground - Completes the electrical circuit.

3. Control - Receives the PWM signals.

These connections are typically made through a microcontroller such as an Arduino or a similar device capable of generating PWM signals.

How PWM Works

PWM involves sending specific signals to the servo to adjust its angle. By varying the width of these pulses, you can precisely determine the servo's position. For example, a pulse width of 1 millisecond might move the servo to 0 degrees, while a pulse width of 2 milliseconds could turn it to 180 degrees. This method allows for fine control over the motor's movement.

Using a microcontroller, you can program these signals to make the servo move as desired, providing an intuitive interface for robotics and automation projects.

Question 2.

Why is the SG90 servo motor considered affordable?

The SG90 servo motor is often deemed affordable due to its budget-friendly price point, making it highly accessible for those on a tight budget. This financial accessibility is especially attractive for hobbyists and students who need cost-effective components for their various projects. Additionally, its affordability doesn't compromise quality, ensuring users receive reliable performance without breaking the bank. Thus, the SG90provides a perfect balance of cost and utility, catering to both educational and recreational needs.

Question 3.

What voltage range is suitable for operating the SG90 servo motor?

To ensure optimal performance, the SG90 servo motor should be powered within a voltage range of 4.8 volts to 6 volts. This range allows the motor to function effectively with most standard power supplies found in RC models and various electronics projects. Avoid using voltages outside this range to prevent any potential damage to the servo.

Question 4.

What is the significance of the built-in potentiometer in the SG90 servo motor?

The built-in potentiometer in the SG90 servo motor plays a crucial role in its functionality. It provides essential feedback on the motor's position, enabling precise control and stability. Here's why it matters:

• Accurate Positioning: By constantly monitoring the servo's angle, the potentiometer ensures that the motor can adjust to maintain its designated position with high accuracy.

• Error Correction: The feedback mechanism allows the servo to detect any deviations from the target position and make real-time corrections, enhancing overall performance.

• Smooth Operation: This constant feedback loop contributes to smooth and reliable movements, making the SG90 ideal for applications requiring precision.

In summary, the potentiometer is vital for the SG90 servo's ability to deliver reliable and repeatable movements.
