Class BO.io.Servo
Creates an interface to a Servo motor. Use this object to set
the angle of the servo head. You can simply specify and angle between
0 and 180 degrees and the servo head will rotate to that angle. See
Breakout/examples/actuators/servo.html for an example application.
You can also use this with a continuous rotation servo. See the
description for the angle property for use with a continuous rotation
servo.
Defined in: Servo.js.

Class Detail
BO.io.Servo(board, servoPin, minAngle, maxAngle)
Creates a new Servo.
- Parameters:
- {IOBoard} board
- A reference to the IOBoard instance that the servo is attached to.
- {Pin} servoPin
- A reference to the Pin the servo is connected to.
- {Number} minAngle
- The minimum angle the server can rotate to (default = 0).
- {Number} maxAngle
- The maximum angle the server can rotate to (default = 180).
Field Detail
{Number}
angle
Set the angle (in degrees) to rotate the server head to.
If you are using a continuous rotation servo, a value of 90 will stop the servo. A value of 0 (or < 90 depending on the servo) will cause continous clockwise rotation and a value of 180 (or > 90) will cause continuous counter-clockwise rotation. If your motor does not come to a full stop when setting 90 degrees, you will need to adjust the servo (there is typically a screw on the motor) to adjust
