The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are controlled by an Arduino-based microcontroller that ...

What if you could *see* UV radiation before it has the potential to cause harm? A novel color-changing ‘living’ sensor could make this a reality, revealing exposure to damaging UV light and paving the ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Abstract: 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, ...

Abstract: In this study, red and green quantum dot color conversion layer was successfully fabricated using inkjet printing (IJP) technology on a blue micro-light-emitting diode (Micro-LED) backlight.
