Abstract: In this paper, a high-precision rotary encoder based on a sinusoidal transmissive pattern (STP) is proposed for detecting shaft rotation. The STP disk can be realized by coating bell-shaped ...

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 ...

Rotary encoders are electromechanical transducers that convert angular displacement into corresponding electrical signals interpretable by digital systems. This article specifically focuses on panel ...

We live in an age of downsizing in the automotive world. Super and hypercar manufacturers like McLaren and Ferrari are ditching big-capacity, high-cylinder count engines in favor of boosted V6 and V8 ...

Precision of rotational and linear measurement underpins motion control systems, and optical encoders are a mainstay in delivering this. Converting mechanical motion into digital signals enables ...

This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 8 decoders can be read over I2C. The PCF interrupt line can be used to detect changes in the ...

Manufacturers need encoders, but they don’t really want to think about them. Encoders are arguably one of the most necessary sensors in manufacturing, but many aren’t sure what to consider when ...

Electrical contacts in mechanical pushbutton switches often make and break contact several times when the button is first pushed. A debouncing circuit can remove the resulting ripple signal to provide ...
