  • 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
