How It Works
The SG90 servo receives a PWM (Pulse Width Modulation) signal from a microcontroller. The pulse width determines the desired shaft position, and the internal control electronics rotate the output shaft to that angle while continuously maintaining the position. This makes the servo ideal for applications requiring precise angular movement, such as robotic joints, steering systems, pan-tilt mechanisms, and automated actuators.
