What is a rotary encoder? A rotary encoder looks like a potentiometer, but it is fundamentally different. A rotary encoder can rotate freely unlike a potentiometer and instead of variating resistance, ...

Not every project has to be complicated– reinventing the wheel has its place, but sometimes you find a module or two that does exactly what you want, and the project is more than halfway done. That ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

Depending on the circles you run in, it can seem like the mechanical keyboard community is all about reduced layouts, and keebs without ten-keys are about as big as it gets. But trust us, there’s ...

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

Lika Electronic's EHO36, EHM36, and EHO37C rotary absolute encoders are built in a very compact and rugged 36-mm housing and feature 6-mm solid and blind hollow shafts. Their small footprint and ...
