In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

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, ...

Our ability to see and distinguish colors is surprisingly limited to our central vision. Because of the distribution of cones on the retina, our sensitivity to colors decreases rapidly as a function ...

The designers at Lightspark write: Humans can’t reliably recall colors. This is a simple game to see how good (or bad) you are at it. Dialed shows you a color for 5 seconds, then asks you to recreate ...

A viral trend called Project Pan, in which influencers and laypeople alike show off their well-used skin care products and makeup, is exploding on TikTok. The challenge is to “hit pan” — to reach the ...

United States Customs and Border Protection is paying General Dynamics to create a prototype of “quantum sensors” alongside a “database with artificial intelligence” designed “to detect illicit ...

The Vivo X300 Ultra is tipped to debut with a new 5MP multispectral sensor aimed at dramatically improving color accuracy for photos and video, alongside major camera hardware upgrades. It’s expected ...

Is the Arduino Uno Q the missing piece in your next project? With its hybrid design that fuses the precision of a microcontroller with the flexibility of a Linux-based single-board computer, this ...

A portable biosensor developed at La Trobe University may allow rapid, on-site detection of toxic "forever chemicals" in water, removing the need for samples to be sent to specialist laboratories. The ...

It’s that time of the year. The leaves are starting to change colors. This week the National Weather Service in Atlanta shared the satellite image above showing fall foliage changes in the Appalachian ...
