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

Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and ...

MicroPython is a well-known and easy-to-use way to program microcontrollers in Python. If you’re using an Arduino Uno Q, ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

Once you’ve found the best LED face mask, yes you may look as though you've stepped out of an Alfred Hitchcock thriller, but actually, what it's doing to improve the appearance of your skin is far ...

How do these popular skincare devices really stack up against one another?

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 ...

This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...

Infrared Audio Communication is a method of transmitting sound wirelessly using pulses of invisible light rather than radio waves. It works by modulating the intensity of an IR LED to match the ...

Abstract: Nowadays, long-wavelength infrared (LWIR) HgCdTe infrared detectors are developing towards high operating temperatures. There remains a lack of knowledge on the operational mechanism of LWIR ...

Abstract: Glucose plays an important role in the field of biology because it is the main source of energy for life activities. Detection of its concentration is widely used in food industry and ...
