| Video Discription | Even though LED's are everywhere, there's still the question - how do LED's actually work? Like... deep down on a molecular level? Well, we go over how these amazing LEDs work by discussing how the electrons lose energy, emit photons, and how scientists and engineers get specific colors. We also go over the way the semiconductor material is packaged into something that we can use. The written tutorial is also available on CircuitBread here - https://www.circuitbread.com/tutorials/how-does-an-led-work If you find this interesting, subscribe to the CircuitBread channel for more videos on intermediate electronics!
