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 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 ...

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 ...

A team led by La Trobe University has drawn inspiration from nature to develop a breakthrough sensor that can rapidly track ...

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 ...

Accurately measuring small shifts in biological markers, like proteins and neurotransmitters, or harmful chemicals in the ...

Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative study ...

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, ...

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.

STMicroelectronics and Leopard Imaging have introduced an all-in-one multimodal vision module for humanoid and other advanced robotics systems. Combinin ...
