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, ...

It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying ...

CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

CU Boulder researchers have engineered ultra-high-performance optical microresonators that trap and amplify light with remarkable efficiency, paving the way for powerful next-generation sensors.

Ikea has launched a new affordable LED light with a built-in motion sensor in Europe, and it appears to be primarily used as a night light. It joins Ikea’s wider range of budget-friendly lighting ...

Electrical engineers at Duke University report they have built a record-setting pyroelectric photodetector that uses trapped light in a plasmonic nanogap to capture a signal in just 125 picoseconds ...

The LITOM 300 LED delivers genuine 2500-lumen output across a 270-degree beam angle, covering wide areas like driveways, backyards, and garage entries without dark spots. The three-head design lets ...
