Class AccelHTSensor
java.lang.Object
lejos.nxt.I2CSensor
lejos.nxt.addon.AccelHTSensor
- All Implemented Interfaces:
- SensorConstants, Accelerometer
public class AccelHTSensor
- extends I2CSensor
- implements Accelerometer
Class to access the HiTechnic NXT Acceleration / Tilt Sensor (NAC1040).
Some sensors seem to be badly calibrated, so 0 is not always level.
