Servo motors and Arduino work together through a process of signal transmission and feedback control. The Arduino sends a Pulse Width Modulation (PWM) signal to the servo motor, which interprets this signal to adjust its position.
Pulse Width Modulation (PWM)
PWM is a technique used to control the amount of power delivered to a device by varying the width of a pulse. In the context of servo motors, the width of the pulse determines the position of the motor shaft. According to research by the IEEE, PWM is a highly efficient method for controlling servo motors, providing precise and energy-efficient operation.
The Control Process
- Signal Generation: The Arduino generates a PWM signal with a specific pulse width.
- Signal Transmission: This signal is sent to the servo motor through a control wire.
- Position Adjustment: The servo motor interprets the pulse width and adjusts its internal circuitry to move the motor shaft to the corresponding position.
- Feedback Loop: A potentiometer inside the servo motor provides feedback to the control circuit, ensuring the motor reaches and maintains the desired position.
Advantages of Using PWM
- Precision: PWM allows for highly accurate control over the servo motor’s position.
- Efficiency: PWM is an energy-efficient method of control, reducing power consumption.
