How to lighting the RGB LED

Install Library

  1. Install library from github:
  • Librarys:[Adafruit_NeoPixel] from Adafruit
  • Download libraries and put it in the libraries folder in the installation directory of the Arduino IDE
 


  1. Install Library by Manage Libraries:

Programe Code

  • Open Arduino IDE

click 'file'->'Example'->'Adafruit NeoPixel'->'simple' to open the example

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

And download it(Set the serial port and board)
