This project demonstrates a low-cost intelligent traffic signal system using Arduino and ultrasonic sensors to reduce congestion caused by fixed-timer traffic lights. Four HC-SR04 sensors detect ...
More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...
The rise of at-home beauty treatments has ushered in a new era of high-tech skincare, with red light therapy devices fast becoming the gold standard. Leading the charge? The best LED face masks. While ...
We’ve reached peak LED face mask culture. Every other video on my TikTok is of someone sporting a Scream-esque mask. There's something about the glow of these skin-rejuvenating devices that just make ...

This library is to control the I2C PCA9634 PWM extender. The 8 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM signal ...
"Windup" occurs when the integral term grows indefinitely while the actuator is saturated (at max limit). Standard PID calculates d(Error)/dt. This library calculates ...
Abstract: Reinforcement Learning is a machine learning method that has been adopted in smart traffic lights to reduce traffic congestion effectively. The algorithm is employed as an agent, like a ...
Abstract: Urban traffic backups often lead to significant delays for emergency vehicles, such as ambulances, fire trucks, and police cars, which can have major consequences. According to a World ...
