Programe Code
- Open Arduino IDE
click 'file'->'Example'->'Adafruit NeoPixel'->'simple' to open the example
- 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
And download it(Set the serial port and board）
