In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

LED lighting technology is increasingly adopted for its energy efficiency, durability, and longevity, making it an ideal solution for modernizing urban areas and developing smart city infrastructures.

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...

Samsung seemingly came out of nowhere with its "LED TV" range. Yet, despite the name, the technology is more familiar than you'd think. Philip Wong is an A/V, PC, photography and gaming enthusiast.

The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...
