循環「定義」值

我在許多#define值中獲得了RGB顏色（HEX）。我想循環每種顏色 - 我的意思是：顯示第一種顏色 - 延遲（1000） - 第二種顏色 - 延遲（1000） - 第三種顏色等。是否有可能通過如此多的#define來實現？而如何做到這一點...循環「定義」值

#define AQUA "#00ffff" 
    #define AZURE "#f0ffff" 
    #define BEIGE "#f5f5dc" 
    #define BLACK "#000000" 
    #define BLUE "#0000ff" 
    #define BROWN "#a52a2a" 
    #define CYAN "#00ffff" 
    #define DARKBLUE "#00008b"

    #define RED "#ff0000" 
    #define SILVER "#c0c0c0" 
    #define WHITE "#ffffff" 
    #define YELLOW "#ffff00" 

int redPin = 9; 
int greenPin = 10; 
int bluePin = 11; 


void setup() { 

Serial.begin(9600); 
} 

void loop() { 

    String hexstring = AQUA; 
    long number = (long) strtol(&hexstring[1], NULL, 16); 
    int r = number >> 16; 
    int g = number >> 8 & 0xFF; 
    int b = number & 0xFF; 

setColor(r,g,b); 

Serial.print("red is "); 
Serial.println(r); 
Serial.print("green is "); 
Serial.println(g); 
Serial.print("blue is "); 
Serial.println(b); 


} 

void setColor(int red, int green, int blue) 
{ 
analogWrite(redPin, red); 
analogWrite(greenPin, green); 
analogWrite(bluePin, blue); 
}

這是不可能的做任何定義的數量。用你想要的值創建一個數組，然後遍歷它。

char *colorarray[] = {AQUA, AZURE, ...};

此外，您應該考慮將顏色存儲爲十六進制值而不是字符串，因爲它們將佔用較少的空間。
