RyzoBee today announced that its Root Series is planned to launch on Kickstarter in Q2 2026 for the North American and European markets (timing subject to confirmation). In response to growing ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

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 ...

You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...

Blue light is a high-energy part of visible light from the sun, screens, and light-emitting diode (LED) bulbs. Your cornea and lens don’t block blue light the way they block ultraviolet (UV) rays.

Tyler has worked on, lived with and tested all types of smart home and security technology for over a dozen years, explaining the latest features, privacy tricks, and top recommendations. With degrees ...

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 ...

Abstract: In this paper, we aim at exploring the performance limits of passive indoor target localization utilizing multiple light-emitting diode (LED) transmitters embedded into the ceiling and ...

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, ...
