Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

They're reference designs for a reason.

What if you could get an instant SMS alert the moment a fire or smoke is detected at home or office? Through this project tutorial, you can build a fire and smoke alarm system using Arduino UNO R4 ...

Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

This engineer doesn’t use nail polish, but his wife does. And he deals with plenty of PCBs. What do these things have in ...

Discover the surprising way a magnet and coil can power an LED! In this video, we explore the fascinating physics of electromagnetic induction, showing how moving a magnet through a coil of wire can ...

ViBRANT, a surrogate nuclear reactor, simulates neutron behavior with light to support safe development of advanced ...

A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of ...

Once upon a time, the cathode ray tube was pretty much the only type of display you’d find in a consumer television. As the analog broadcast world shifted to digital, we saw the rise of ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
