“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the available rotary encoder sketches and none of ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

It’s safe to say that few people still use rotary phones on a daily basis. Hell, most of us don’t even use landline telephones anymore. But just because these classic phones are no longer being used ...

Rotary encoders connect to a shaft and, as the shaft rotates, the encoder outputs pulses. These are used to determine the speed of the object. By counting the amount of pulses per one full turn of the ...
