int led[4][4]={{2,3,4,5},{6,7,8,9}};
void setup() {
for(int i = 2; i<=10;i++)
{
pinMode(i,OUTPUT);
}
// put your setup code here, to run once:
}
void loop() {
for(int rows = 2; rows <= 5; rows++)
{
for(int colums = 6; colums <= 9; colums++)
{
digitalWrite(led[rows][colums],HIGH);
delay(500);
digitalWrite(led[rows][colums],LOW);
}
}
// put your main code here, to run repeatedly:
}
this is my code what am i doing wrong?
