A lot of making goes on in this community these days, but sometimes you’ve just gotta do some old fashioned hacking. You might have grabbed an old Speak and Spell that you want to repurpose ...

This project demonstrates the interfacing of an Infrared (IR) sensor with the Arduino UNO R4 WiFi to detect obstacles in real-time. It utilizes digital signal processing to monitor the environment and ...

In this tutorial we will learn how to program serial port of a windows PC using Java programming language. The PC will communicate with an Arduino connected to the USB virtual Serial port of the PC ...

Abstract: Metastability can arise whenever a signal is sampled close to a transition, leading to indecision as to its correct value. Synchronizer circuits, which guard against metastability, are ...

Abstract: Intelligent reflecting surface (IRS) is an enabling technology to engineer the radio signal propagation in wireless networks. By smartly tuning the signal reflection via a large number of ...
