 #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）
