This is my code.

int latchPin = 8;
int clockPin = 12;

int dataPin = 9;
int dataPinRed = 10;
int dataPinGreen = 11;

int powerPin = 13;

byte data;

byte dataArray[22];

int Red = 1;
int Green = 2;
int Orange = 3;

void setup() {

  pinMode(latchPin, OUTPUT);
  pinMode(powerPin,OUTPUT);
  digitalWrite(powerPin,HIGH);
  
  myarray();

}

void loop(){
  
  for(int i = 0 ; i <= 5000 ; i++){
  dotshow(random(1, 9),random(1, 9),random(1, 3));
  delay(1);}
  
  
  
  for(int c = 1 ; c <= 3 ; c++){
  for(int i = 1 ; i <= 8 ; i++){
  rowshow(i,c);
  delay(100);}
  for(int i = 8 ; i >= 1 ; i--){
  rowshow(i,c);
  delay(100);}
  dotshow(0,0,c);
  delay(500);
  }
  
  for(int c = 1 ; c <= 3 ; c++){
  for(int i = 1 ; i <= 8 ; i++){
  colshow(i,c);
  delay(100);}
  for(int i = 8 ; i >= 1 ; i--){
  colshow(i,c);
  delay(100);}
  dotshow(0,0,c);
  delay(500);
  }
