CHAPTER 2Basic LED Circuits:How to Make an LED Flashlight
TO CREATE BRILLIANT LED PROJECTS, YOU NEED A basic understanding of the components you are working with. Thus, this chapter first explains what light-emitting diodes (LEDs) are and how you can start to use them in your projects. This then leads to your first project, which shows you how to make an LED flashlight.
What Are Light-Emitting Diodes?
LEDs are relatively low-cost, solid-state illumination devices that have many advantages over their standard incandescent light bulb counterparts. These advantages include fast switching times, no filament to blow, low operating current, long operating life, and fairly cool operating temperatures. These key benefits make LEDs a popular choice for ...
