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

Error creating thumbnail: Unable to save thumbnail to destination

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

Error creating thumbnail: Unable to save thumbnail to destination

And download it(Set the serial port and board）
