Why doesn't this work? Shouldn't the display constatly switch between zero and one? It displays zero and does nothing else. Newbie here.
// C++ code
//
void loop() {
digitalWrite(a,HIGH);
digitalWrite(b,HIGH);
digitalWrite(c,HIGH);
digitalWrite(d,HIGH);
digitalWrite(e,HIGH);
digitalWrite(f,HIGH);
delay(1000);
digitalWrite(b,HIGH);
digitalWrite(c,HIGH);
delay(1000);
}
