The Universal Gauge is the second of the Bioloid beginner tutorials and as such is another very simple tutorial. Again the only components used are the CM-5 control module and a single servo. When the device is created the user has control over the speed at which the arm of the device actuates back and forward. This is done using the U and D buttons on the CM-5 control unit.
Again this is a very simple tutorial to get the user used to constructing simple mechanisms and also shows the control which the user has over the servos. This can be very useful when more complex mechanisms are created which may require very rapid motion or very slow careful actions.
