Chapter 7. NeoPixel Lamp
In this chapter, you will build an LED light that can be controlled from an app on your phone.
Hardware
The following hardware is required:
-
Arduino Uno
-
AC adapter, 9V or 12V
NeoPixels
This project uses NeoPixel LEDs. NeoPixel is Adafruit’s name for its individually controllable WS2812 LEDs. Each NeoPixel in a ring can be set to one of 16 million colors. For this project, all the lights will be the same color. NeoPixels can be sensitive to voltage, so it’s important to keep them supplied with 5V or less. The NeoPixels are also sensitive to CPU clock timing, but the Adafruit Arduino library handles that for us.
