Chapter 10. LEDs

Chapter 10. LEDs

In this chapter, you're going to learn about LEDs. You'll see how to select them, test them, and why no self-respecting robot would reject them.

Light Emitting Diodes (LEDs) are modern miracles. They're long lasting, impact resistant, inexpensive, cool to the touch, lightweight, and come in a wide variety of colors and sizes. LEDs are perfectly suited for battery-powered devices due to their low-voltage and low-current requirements.
