# CRServo

A Continuous Rotation Servo (CRServo) is a type of servo motor designed to rotate continuously in both directions. Unlike standard servos, which have a limited range of motion, CRServos can spin indefinitely.

Key Characteristics:

* Continuous rotation: Can spin in both clockwise and counterclockwise directions.
* Speed control: Typically controlled by setting a power level between -1.0 (full speed reverse) and 1.0 (full speed forward).
* No positional feedback: Unlike standard servos, CRServos generally don't provide feedback on their position.

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 motor control and ease of programming.

Provides the power of a servo.

Key points:

* Return value: A floating point value from -1.0 to 1.0
* Usage: Used to check the power of a servo. Crucial for precise motor control.

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.&#x20;

Controls the power the servo receives, determining its speed and direction.

Key points:

* Value range: Accepts a floating-point value between -1.0 and 1.0.
* Direction: Positive values move the servo forward, negative values move it backward.
* Magnitude: The absolute value of the power determines the servo’s speed.
