⚙️ How the Tower Pro SG90 Servo Motor Works
The Tower Pro SG90 Servo Motor operates using PWM (Pulse Width Modulation) control signals. Unlike DC motors that rotate continuously, a servo motor rotates to a specific angle based on the width of the input pulse.
-
A pulse width of ~1 ms moves the servo to 0°
-
A pulse width of ~1.5 ms moves it to 90°
-
A pulse width of ~2 ms moves it to 180°
This precise control makes the SG90 ideal for applications where accurate positioning is required.
