Why do I need this?
why do I need to use the "int" again on counterLED below void loop, if I had already used it in void setup? It says that counterLED wasnt enabled in this scope, but I thought the int counterLED inside the for loop at void setup would have done the job.
I fattened the code that Im trying to understand.
The code:
int counter;
int delay1 = 666;
void setup() {

The code:
int counter;
int delay1 = 666;
void setup() {
- this is the first time is use int*
for(int counterLED=2;counterLED<=6;counterLED++) {
pinMode(counterLED, OUTPUT);
}
Serial.begin(9600);
}
- why is the int needed here again for the same variable?*
for (int counterLED=2; counterLED<=6;counterLED++) {
digitalWrite(counterLED, HIGH);
delay(delay1);
digitalWrite(counterLED, LOW);
}
