Hardware Connection
Take Nezha breakout board for an example.
Connect the servo to S1 port.
Add the Extensions
Click "Advanced" in the MakeCode drawer to see more choices.
For programming Nezha breakout board, we need to add the extensions. Click "Extensions" on the bottom of the drawer and search with “nezha" to download the extension.

Result
The 360° servo rotates to 0° when button A is pressed and rotates to 360° when button B is pressed.
Note
When using a servo, you should adjust the servo angle and adjust it according to the case requirements for verification. After the verification is completed, install the corresponding structural parts to prevent the servo from being blocked and burning.Note: When using a servo, you should pay attention to whether the servo is blocked. If the servo is blocked, there may be a risk of burning.
Note: When using a servo, you should pay attention to whether the servo rotation action needs to be delayed. The servo rotation takes time to execute. If a new servo command appears during the servo execution, it will overwrite the previous servo rotation command, resulting in the servo not rotating in place.
