How do you activate servo?

To activate a servo motor, you typically need a microcontroller (like an Arduino) and a power source. Connect the servo's control wire to a PWM-capable pin on the microcontroller, and power the servo from an appropriate voltage source. In your code, send a PWM signal to the control pin to specify the desired position of the servo, usually ranging from 0 to 180 degrees. Make sure to set up the necessary libraries and functions to manage the servo's movement in your programming environment.
