LED Basics - Electronics with Becky Stern | DigiKey

Learn how LEDs work and how to pick the best ones for your projects. Light Emitting Diodes are electronic components that give off light when electrical current flows through them. They only light up when hooked up one way, so Becky Stern will show how to test the polarity of LEDs with a coin cell battery. Learn about the different types of RGB and addressable LEDs, and get ready to create your own basic LED circuits.
