Abstract: This work presents a cost-effective approach to implementing programmable logic controllers (PLCs) for educational use, using commercial microcontrollers (Arduino UNO, ESP8266 NodeMCU) and a ...
The app is audio-only and doesn't show any text. It's perfect for catching up on notes or dense documents. Google's smart ...
The Council for the Indian School Certificate Examinations (CISCE) has released the ISC Computer Science (Subject Code - 868) for the Year 2027 evaluation cycle. It is designed specifically to make ...
UNSW researchers have developed a novel hydrogen fuel cell design that improves water management. We take a closer look.
To sharpen an auger bit, you need a specialized auger-bit file. Hold the auger bit upright in a vise, then file the bit’s lip with the file’s edge [1]. Turn the auger bit in the vise and sharpen the ...
How microcontrollers and single-board computers coordinate high-speed RF acquisition and generation. How SCPI and UART commands let simple controllers use advanced measurements without FPGA ...
You don’t need expensive software for basic PDF tasks. In fact, all you need is a handful of free web-based apps.
Update: This ESP32 drone project has now evolved and is called LiteWing - ESP32-based programmable Drone. We have improved the design and functionality, you can now program and control the drone not ...
Aim: detect electric phase zero-crossing, to PI (PID) control mono/three-phase electric motors. Full-wave rectifies mains signal and compares it to a near-ground VDC signal to produce a 'zero' ...
Current signals of 4-20 mA are commonly used in industrial applications to transmit process signals to controllers. Compared to analog voltage signals or digital communication, the current loop ...
