I have connected 2 LEDs one in pin 12 and another in pin 11
How do I blink them alternatively...??
If LED a is on then LED b is off
and vice versa...
Something like this:
void setup(){
pinMode(11,OUTPUT);
pinMode(12,OUTPUT);
}
void loop(){
digitalWrite(11,LOW);
digitalWrite(12,HIGH);
delay(500);
digitalWrite(11,HIGH);
digitalWrite(12,LOW);
delay(500);
}
This is untested and uncompiled code, but should not give errors.
a simple thing
but didnt come to my mind...
I was just making it complicated with if and else statements...
