In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

Abstract: This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display ...

Arduino Nesso N1 is a new ESP32-C6 IoT development kit with not only 2.4 GHz WiFi 6, Bluetooth LE, and an 802.15.4 radio for Zigbee/Thread/Matter, but also a LoRa radio and an IR transmitter for smart ...

What if your muscles could do more than just move your body? Imagine flexing your arm to scroll through a webpage or clenching your fist to control a robotic arm. It sounds like something out of a sci ...

Schematic of the TCM–MWG–TED structure. The upper thermochromic (TCM) layer provides visible camouflage with high transparency in the 8–14 μm mid-infrared range. The middle layer consists of a ...

InfraWeeder, created by Brühwiler Maschinen AG, is making waves with its innovative approach to weed control. They focus on the environmental and practical benefits of using infrared technology for ...

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on a ...

Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra. NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to ...

Military-grade infrared vision goggles use detectors made of mercury cadmium telluride, a semiconducting material that’s particularly sensitive to infrared radiation. Unfortunately, you need to keep ...
