Servo
==========

Servo is a position (angle) servo device, which is suitable for those control systems that require constant angle changes and can be maintained. It has been widely used in high-end remote control toys, such as airplanes, submarine models, and remote control robots.

Now, try to make the servo sway!

**Wiring**

* The brown wire of the servo is GND, the red wire is VCC and the yellow wire is signal.
* Connect **VBUS** (not 3V3) to the power bus of the breadboard.


**Code**

After connecting Pico, click the **Start** button and the code starts to run. If necessary, press the Servo Arm into the Servo output shaft, then you can see the Servo Arm swinging back and forth from 0° to 180°.
