Learn Electronics: The Light-Emitting Diode (LED)

Course Overview:

The Light-Emitting Diode (LED) is a really fun component that creates light. When you know how it works and how to use it you can create your own flashlight, model train indicators, toys with lights, party lights, Christmas tree lights, and much much more. Every project becomes better with LEDs!

In this course, you'll learn the basics of LEDs so that you can choose resistors for LEDs with confidence, power up an LED strip, and much more. You'll play with LED brightness, color mixing, and combine several LEDs in one circuit.
