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, ...

LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from ...

Abstract: In this paper, a cost-effective architecture based on Flyback topology is proposed for both constant current (CC) output for LED drive and constant voltage (CV) output for auxiliary (AUX) ...

Abstract: Visible light communications (VLCs) are a promising technology to address the spectrum crunch problem in radio frequency networks. A major advantage of VLC networks is that they can use the ...

Multicore processing boosts performance and energy efficiency in many coding situations. Bare-metal algorithms further ...

Back in 2017, Hackaday featured an audio reactive LED strip project from [Scott Lawson], that has over the years become an ...

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, ...
