The LEDs you are most likely to use are the through hole LEDs with two legs. There are lots of LEDs that are small and hard to solder but these are easy to use with a breadboard because they have …

The National Institute of Standards and Technology (NIST), is developing a Color Quality Scale that does a better job of measuring the color rendering abilities of white light LEDs.

Discover what polarity is, which parts have it, and how to identify it. This tutorial will explain how to use and convert between the standard metric prefixes. So you've come to the sensible conclusion that …

LEDs (that’s “ell-ee-dees”) are a particular type of diode that convert electrical energy into light. In fact, LED stands for “Light Emitting Diode.” (It does what it says on the tin!)

LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, and greater durability and reliability.

LM-79-08, Electrical and Photometric Measurements of Solid-State Lighting Products, describes approved methods for measuring several attributes of LED products, including total flux, electrical …

We will be working with different colored LEDs, and will explore the relationship between the colors of light emitted and the voltage, current, and power needed to light them up.
