That was, by far, the best explanation of how LEDs work I have ever seen. Super in depth, while not talking over our heads.

I got here referenced from Derek's ( Veritassium ) video "Why It Was Almost Impossible to Make the Blue LED". So cool.

Well done. This explained Diodes in minutes what took days for my professor in college to do back in the ‘80s.

You are wonderful, man. Explaining such a wide spectrum of electronics, in such brief lucidly.

Another LED type that I learned about a few weeks ago is called an addressable LED. It’s a bit beyond this video, but worth noting for the advanced users as it allows multiple LEDs to be controlled at different colors each using only one signal pin on a microcontroller. It is a LED with an internal microcontroller that can be gotten as either RGB or RGBW and is controlled by a high low signal. The LEDs are chained in sequential order by their signal pins. To control them, a signal is sent containing the information for all the LEDs in the chain. The first LED removes its instructions and then sends the remaining signal to the next LED. These LEDs can be bought individually or in LED strips.

LED's are basically amazing stuff. When I was little I only saw LED in red or green, and they were very dim, only useful for indicator lights on various machines. Then someone invented blue LED and now LED has basically replaced light bulbs.

this is much better than textbook definitions, he explains everything perfectly

I love how, when adjusting the ratios of GaAs and GaP (GaAsP), you had the audience GASP every time the light came on. Subtle, yet beautiful.

Best video i have seen so far informing us about LEDs. Thanks very much for high quality content and the effort put into it. I really appreciate you supported your theoretical background together with circuit diagraghms and also making it on breadboards just to let us see how it looks. It definitely would tale a lot of effort and time. That is very much appreciated.

This is one of the best videos I've ever seen. Easy to digest for any level of familiarity of sciences, with amazing infographics. Keep up the great work.

This was extremely fun and engaging, thank you so much for the high quality content mate

I absolutely love the pace and information density in your videos!

hands down the best explanation of LEDs from start to finish. this needs to go on the reference shelf. thank you sir.

I have learned that before. But the way you explained, makes the learning more enjoyable/fun making electronics more interesting for newbies. Very well explained and great video.

An incredibly well detailed video& very well put together. Cheers. 👍

The explication of the n and p type materials was so clear. I don’t think I’ve ever seen it done that well. Bravo!

Brilliant video, Paul, full of explanation and detail. Just the thing to get young brains excited. Thanks for sharing.

Amazing super condensed info about LEDs. Best video on this topic I've ever seen.

My teacher used your video in class.
