From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

This project provides a simple and practical solution using an Interactive Voice Response System (IVRS) that works completely ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Back in 2017, Hackaday featured an audio reactive LED strip project from [Scott Lawson], that has over the years become an extremely popular choice for the party animals among us. We’re fascinated to ...

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

Abstract: This paper proposes a nonlinear approach of controlling the luminous intensity and correlated color temperature (CCT) of white light-emitting diode (LED) systems with dual color temperatures ...

Abstract: This paper proposes a closed-loop nonlinear scheme for precisely controlling the luminosity and correlated color temperature (CCT) of a bicolor adjustable light-emitting diode (LED) lamp.

Gone are the days when remote desktop and remote control are reserved for IT departments or enterprise teams. They have become part of how ordinary people work, create, and solve problems in daily ...

A time domain reflectometer (TDR) is a useful tool to have for finding faults in a wiring harness. However, they don’t come cheap, putting them out of reach for many shadetree mechanics that like to ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...
