Angle Sensor and analog RPM Gauge in NXT-G

Saturday, February 12th, 2011

The HiTechnic Angle Sensor can give you three pieces of data regarding the axle input: the angle, accumulated angle and RPM. In this blog post I demonstrate the RPM feature of the sensor and present a program that displays an analog RPM gauge on the NXT screen. The program also allows you to control the motor on port A of the NXT so you can test the gauge using a motor. If you have access to other LEGO motors, such as PF motors, you can use those as well with the Angle sensor.
