💥 Essential for electronic novices | LED is not an ordinary small bulb! comics Who knows! I always thought LEDs were just little light bulbs 😵‍💫 It turns out that he is a semiconductor giant! 🟡Figure 1 | Unlock the diode family Light-emitting LED | Electric energy → Light energy✨ UV UV LED | Nail Curing | Sterilization and Disinfection 🦠 Ordinary diode | Unidirectional conduction Positive energization turns on the light. Negative energization directly shuts it down! Lighting, screens, and medical devices are everywhere! 🔵 Figure 2 | The Mystery of LED Luminescence + Wiring Lightning Protection Glowing is not magic! Electronic transitions release photons ⚡ 3 quick tips to distinguish positive and negative poles 👇 ✅ Long leg = positive pole | Short leg = negative pole ✅ The flat side of the shell = negative electrode ✅ Connect the internal small electrode to the positive pole ⚠️ Control the voltage and current, otherwise the components will be burned directly! 🔷Figure 3 | PN junction bottom layer dry goods P-type and N-type form a PN junction Electrons + holes collide and release energy 🔥 Three major functions of diodes: Unidirectional conduction | Low power consumption | Ultra-fast response Mobile phones, street lights, and car headlights are all in use! Friendly comic for beginners with no foundation✅Introduction to circuits 💬 Ask: Have you ever fallen into the trap of connecting LEDs in reverse while doing experiments?

Today I finally assembled the Fibonacci 256 Expanding HDR that I got from Evil Genius Labs nearly two months ago. The colors are really vivid and a lot easier to photograph than my LED cube. #EvilGeniusLabs #Blinky #LED

Paging any "LED neon" experts out there in Fedi-land, please...? I plan on replacing the vinyl lettering in my front fascia board with fake-neon. I think probably the best way of doing this is to laser-cut the channel on MDF, paste it to the back-board, then LED strip with a diffuser pipe channel on top to cope with right angles. At thinnest point the lettering is 8mm width, at thickest it's about 15mm. Logotype cannot be changed. Any pointers please? I'm new to this! 😘 #fedihelp #led #neon

Come to the dark side. Join us. We have chocolate. Also blood. Chocolate and blood. -- More seriously, I fear these sorts of application-specific displays are going to go the way of the dodo. It's gotten to the point where a reasonably large pixel-mapped display is, to a first approximation, free. Slap one of those on top of your MCU board and you're done - no designing a custom panel, laying out LEDs, multipin connectors to run all the LEDs... and the actual usability of the things will probably tank, because then the display is "just software", and we know how excellent white goods makers are at software... #electronics #display #ApplicationSpecific #TaskSpecific #appliance #LED #hobby #chocolate #blood #DarkSide.

Also need to go look up the polarity of an LED. I never remember this. I have looked this up a hundred times. But it does not stick. #led #electronics

Hab mal ein bisschen mit meinen neuen kleinen #LED Scheinwerfern gespielt. Mit Licht an Stellen zu spielen, die sonst eher kein Licht abbekommen ist schon eine spannende Sache :)

I'm sorry, how come some 2W #LED G4 bulbs on Amazon are #energy rating C, some E and some F whilst the 20W halogen is G?! Surely there should be more than 1 grade different for a bulb that draws 10x the power?
