Tired of struggling with regular graters and risking scraped knuckles? A rotary cheese grater could be the faster, safer, and more efficient solution you need. This kitchen gadget isn’t just for chefs ...

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 ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

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 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...

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 ...

Part 1 of this FAQ looked at the optical rotary encoder, a low-cost, high-resolution, easy-to-use sensor for indicating incremental shaft position (although it can be “upgraded” to indicate absolute ...
