ABSTRACT:
This device is a handheld, battery-operated instrument that utilizes light beams to project visible lines for increasing the accuracy in determining angles. A linear potentiometer is incorporated at the pivot point between the two diodes and measures a voltage change based on the angle between the arms of the device.
