Building an automated attendance system using ESP32-CAM is a practical, affordable way to solve this problem for classrooms, ...

Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to tasks at work or baking your own birthday cake. But if you want a specific ...

ESP-FLY DIY kit is a miniature DIY drone kit based on Seeed Studio's XIAO ESP32-S3 board that was initially introduced as a ...

If you are used to coding with almost any modern tool except the Arduino IDE, you are probably accustomed to having on-chip debugging. Sometimes having that visibility inside the code makes all the ...

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 ...

Abstract: The promotion of the HEVC standard has significantly alleviated the burden of network transmission and video storage. However, its inherent complexity and data dependencies pose a ...
