✦ All the info you need right here ✦ In this occasion I'll make a lighting system to be controlled remotely from my rc using Arduino compatible boards, they will take the input from a receiver and ...

Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...

An optocoupler tester is a small device that helps verify whether an optocoupler is functioning properly or has failed. In labs and repair work, optocouplers often fail without clear signs. They may ...

Back in December, Godox unveiled the LiteWafer UP150R Full-Color LED Panel, which is essentially a 2x1-sized panel. Now, they are offering a two-light kit ...

Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

We asked experts about why our LED bulbs seem to die ahead of time. Here are the reasons they gave. Tyler has worked on, lived with and tested all types of smart home and security technology for over ...

A twisted pair of photonic crystals integrated with MEMS can dynamically control the handedness of light on a chip.

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

After all the crashing and burning of Imperial Germany’s Zeppelins in the later part of WWI – once the Brits managed to build ...

Abstract: Photonic crystals (PhCs), as a type of metamaterial, have attracted significant attention due to their ability to control light propagation to enhance the light extraction efficiency (LEE) ...
