How does a Servo Motor Work and How to Interface it with ESP32? A servo motor is a type of motor that is used to control the precise movement of a device. It typically consists of a DC motor, a control circuit, and a feedback mechanism. The feedback mechanism is used to provide information about the position of the motor shaft to the control circuit, which then adjusts the power to the motor accordingly. This feedback loop… |
