New page

==How to lighting the RGB LED==

* Librarys:[[https://github.com/adafruit/Adafruit_NeoPixel Adafruit_NeoPixel]] from Adafruit

* Download librarys and put it in the libraries folder in the root directory of the Arduino IDE

[[file:LightingLED-1.png]]

* Open Arduino IDE
click 'file'->'Example'->'Adafruit NeoPixel'->'simple' to open the example

[[File:LightingLED-2.png]]

We need to change some code,Find the code below in the code

#define PIN 6
#define NUMPIXELS 16

change to

#define PIN 4
#define NUMPIXELS 25
#define LED_POWER 2

Then add the following code to void setup()

pinMode(LED_POWER, OUTPUT);
digitalWrite(LED_POWER, HIGH);

Compile this program
