Detailed Description

Rotation-sensor interface (active mode).

Provide an interface to rotation sensor hardware attached to the RCX

At construction time you specify the RCX connector pad to which the rotation sensor is attached and its initial position (default = 0).

Additionally, RotationSensor provides methods to:

  • enable and disable rotation sensing [on, off]
  • set or read the current position

List of sensor identifiers (IDs).

S1, S2, S3 are connector pads 1, 2 and 3 on the RCX.

Battery is the internal sensor allowing a program to read the current battery voltage in milliVolts
