# Servo

A type of motor that can be controlled to move to a specific angle. It includes a built-in feedback mechanism that allows it to accurately position itself. This makes servos ideal for applications requiring precise control, such as robotics, RC models, and automation.

**set servo.Direction to**

Controls the direction of the servo. The only directions are “FORWARD” or “REVERSE”.

<br>

Key points:

* FORWARD: The power the servo receives is unaltered.
* REVERSE: The power the servo receives is multiplied by -1, reversing its sign.
* Usage: To make setting and controlling the power to servo easier while programming and driving.

**set servo.Position to**

Sets the target position of the servo.

Key points:

* Value: A floating-point value in ticks.
* Usage: A more precise method to control the position of the servo.&#x20;

**Direction**

Provides the current direction of a servo.

Key points:

* Return value: A string value of “FORWARD” or “REVERSE”.&#x20;
* FORWARD: The power the servo receives is unaltered.
* REVERSE: The power the servo receives is multiplied by -1, reversing its sign.
* Usage: Used to check the current direction of a servo. Crucial for precise servo control and ease of programming.

**Position**

Provides the current position of a servo.&#x20;

Key points:

* Return Value: A floating point value in ticks.
* Usage: Crucial for precise servo control, closed-loop control, and position-based actions.

**scaleRange**

Defines a specific range of motion for a servo within its overall potential range.

Key points:

* Restricting movement: Prevents the servo from moving beyond a desired range, protecting mechanical components.
* Simplifying control: Maps desired values to a scaled range, making calculations easier.
* Optimizing performance: Focuses servo control on a specific area of its movement for better precision.
* Usage: Takes two parameters: a minimum and maximum value as a fraction of the full range (0.0 to 1.0). Subsequent set position calls will be scaled to fit within the specified range.
