Electronic Counter with Quadrature Encoder

The counter project was created to read one or two digital or analog sensors and display the running total on an organic LED display.

The speed of an attached DC motor can be controlled by the counter and when a certain count is reached, it can stop. A continuous rotation rotary encoder dial is being featured by this counter with a cut-away view and an explanation of how quadrature encoding works. A number once or multiple times per rotation can be incremented by the counter or decrement a number when something rotates backwards. This counter can also be used in a variety of industrial applications and not be limited to just rotating devices.

A quad encoder is probably the most reliable and convenient sensor for measuring motor rotations as it was attached to the motor shaft. The two types of sensor outputs consist of digital and analog with two sensor inputs. The counter device accepts a square wave signal for digital sensors with a low voltage between -0.5V to 1.5V and a high voltage between 3.5V to 5.5V. The low and high trip points can be set by the user for analog sensor.
