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
