💥 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!

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!

New on the blog. At Cables of Resistance, I ran a workshop asking if we can build hardware without capitalism. I was grieving what AI is doing to open source. Technologists need to see there's no innocent ground under the machine. It was always someone's land.
