Once I had everything ready to go, I flashed the ESP32 with ESPHome. This was pretty simple through the ESPHome web flasher ...

On its 1000-ohm tap it needs only about 3 mA for full scale, so the ESP32 drives it straight from a GPIO with PWM, with no ...

Hello everyone. Have you ever thought, 'I want to take my ideas and turn them into an original gadget'? However, when you ...

Last time, we learned how the holes in a breadboard are connected internally. This time, we will take a detailed look at the "LED" and "resistor," which are the first electronic components to be ...

A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen TVs, augmented and virtual reality headsets, smartphone screens, medical ...

Scientists at the University of Cambridge have achieved what was once considered impossible by electrically powering insulating nanoparticles to create a completely new kind of LED. Using tiny organic ...

Scientists have discovered how to electrically power insulating nanoparticles using organic molecules that act like tiny antennas. These hybrids generate extremely pure near-infrared light, ideal for ...

It’s hard to believe that the first blue LED didn’t arrive until 1993. They look simple, but looks are deceiving (Fig. 1). 1. Image showing a blue InGaN-based LED with gold wire contacts (0.4 × 0.4 mm ...

Both LCD TVs and LED TVs have been on the market for many years. TV-size LCDs gained popularity in the mid-2000s, while LED TVs followed a few years later. The marketing departments for many companies ...

The alphabet soup of TV terminology is overwhelming enough, but you might have seen a particularly confusing term pop up lately: mini-LED. LEDs are already tiny, so what exactly could the "mini" here ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...
