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 ...

Learn how to make a simple hand-cranked power generator from scratch using basic materials like DC motors, a wooden base, an ...

During the acquisition of correct rejection response, rankings of functional connection separated for cortical and subcortical regions, which is predictive of the peak timing of visual information ...

A team of researchers in Japan has developed an artificial intelligence tool called YORU that can identify specific animal behaviors in real time and immediately interact with the animals’ brain ...

Building a DIY Arduino game controller requires specific hardware components. The table below lists all the components required to build the Arduino Uno game controller project. These components are ...

A recent video by Axiometa explores an unusual electronics challenge: driving addressable NeoPixel LEDs entirely in hardware, without any microcontroller or code. Since WS2812-style LEDs normally rely ...

One American company is working to replace a key, rare earth mineral used by the military by using a technology of its own. LightPath Technologies , an Orlando, Florida-based optics and photonics ...

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 ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

A Japanese research team has successfully reproduced the human neural circuit in vitro using multi-region miniature organs known as assembloids, which are derived from induced pluripotent stem (iPS) ...

Abstract: This design proposes a dual color LED control circuit based on TL431 precision adjustable voltage regulator, which can achieve smooth switching of LED color and brightness adjustment. This ...
