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, ...

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

Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

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

It seems like just yesterday that the original Apple Watch hit shelves, and many of the features introduced in 2015 (the Apple Watch's debut year) are still an integral part of the watchOS experience ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

Anyone who is into their skincare will be familiar with retinol by now. The ever-popular ingredient has gained cult-status thanks to its promise of smoother, more youthful looking skin. However, ...

Abstract: This paper proposes a blink recognition system based on frequency-modulated continuous wave (FMCW) radar. First, Fast Fourier Transform (FFT) is applied to intermediate-frequency (IF) ...

Abstract: Epileptic seizures are frequently preceded by subtle physiological and behavioral signals called pre-seizure auras. Detecting these early cues can provide patients and caregivers valuable ...

LED blink using raw register addresses. This is the absolute minimum bare-metal Swift program. It blinks the on-board LED (GPIO25) by writing directly to hardware register addresses.
