We made a digital Measuring Wheel using the rotary encoder in this tutorial. Digital Measuring Wheel can help us measure the length it traverses with millimeter-level accuracy.

A lot of people have used brushless or stepper motors as rotary encoders, but they all seem to do it by using the motor as a generator and looking at the phases and voltages.

It’s a board that turns a rotary encoder into an I2C device. Now, instead of counting rising and falling edges, adding a rotary encoder to a project is as easy as connecting four wires.

A new kind of length counting device based on compensation function is designed. It is composed of the rotary encoders, proximity switches and CPU, etc. This counting device can be used for the paper, ...

Classical theoretical algorithms to calculate rotation speed from incremental encoder information, frequency counting and period counting algorithm, delivers no ...
