Lighting the RGB LED

How to lighting the RGB LED

Install Library

1. Install library from github:

• Librarys:[NeoPixel_Bus] from Makuna
• 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'->'NeoPixel Bus'->'simple' to open the example

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

 const uint16_t PixelCount = 4; // this example assumes 4 pixels, making it smaller will cause a failure
 const uint8_t PixelPin = 2;  // make sure to set this to the correct pin, ignored for Esp8266

• change to

 const uint16_t PixelCount = 25; // this example assumes 4 pixels, making it smaller will cause a failure
 const uint8_t PixelPin = 4;  // make sure to set this to the correct pin, ignored for Esp8266

• Then add the following code to void setup()

 #define LED_POWER      2
 pinMode(LED_POWER, OUTPUT);
 digitalWrite(LED_POWER, HIGH);

• Compile this program

And download it(Set the serial port and board）
