Abstract
An light-emitting diode (LED) meter capable of analog presentations is disclosed. The LED meter includes an LED and a reflective object. The reflective object is capable of reflecting light emitted from the LED. The reflective object is also capable of being moved to and for along a path. The LED meter also includes means for selectively enabling the LED to emit light continuously for a duration that is proportional to a magnitude of measurement.
