Not all poisonous gases have a smell or a color. But a tiny grid of pastel- and candy-colored squares that effectively "sniffs" out hazardous chemicals in the air such as chlorosarin—a highly ...

This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, green, and ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

Here are the best flagship smartphones of 2025 not sold in the US, featuring top-tier cameras, foldable displays, and cutting-edge hardware from China.

I’ve been following Prusa since 2015, when Josef Prusa launched the Original Prusa i3. I was enamored like the rest of you ...

The phone includes a 50MP main camera with a 1-inch Sony sensor, a 50MP ultra-wide, two periscope telephoto cameras (3x and 6x), and a spectral color sensor for better skin tones and color accuracy.

Automated color-detection object sorting has revolutionized several industries, including manufacturing, logistics, and recycling. The systems that use Arduino UNO microcontrollers for color sorting ...

We present a reference-based video color grading framework. Our key idea is to generate a look-up table (LUT) for color attribute alignment between reference scenes and input video via a diffusion ...

This Arduino sketch is a Joystick-controlled RGB LED color mixer. It allows you to adjust the red, green, and blue components of an RGB LED using a joystick ...
