I have a question about array in Arduino. Sorry for bad English. I want to post numbers in array,and I think below code works properly. However,it don't work and corrupted numbers flows in Serial monitor. Even "delay(1000)" don't work.

If I changed "ND_MAC[i]=128;" to "ND_MAC[i]=126;", it works properly. So I'm wondering if this array is char type,but I designate int to array. How to solve it?

int ND_MAC[7];

char i=0;

void setup() {

Serial.begin(9600);

}

void loop() {

for(i=0;i<8;i++){

ND_MAC[i]=128;

Serial.print(ND_MAC[i],HEX);

}

Serial.println();

delay(1000);

}
