The ESP32 keeps finding new jobs in my house.

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

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 ...

Split-flap displays are a great, low-power way to display text to a wide audience. Compared to other display technologies ...

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 ...

Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative study ...

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 ...

While computer monitors seem to be more or less the same once you get past the size and the ports, that’s not really true. Even the most common type, the humble LCD, has a lot of sub-types. And while ...

Abstract: This article introduces an inexpensive Wiegand-sensor-based rotary encoder that avoids rotating magnets and is suitable for electrical-drive applications. So far, Wiegand-sensor-based ...

OptiTrack is an Arduino-based optical encoder system developed for real-time rotation monitoring and pulse counting applications. The system utilizes an infrared (IR) sensor and a slotted encoder ...
