What is the limit of the 'for' function?

Take a look in this code:

Shorten Arduino code where Outputs are repeated to go High and LOW

could make press take an array and count.. const int relayPins[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, A0, A1}; int relayStates[] = {HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH, HIGH}; int delayTime = 100; void Press(int N[], int NumPins) { Serial.println("pressing pins"); for (int i=0;i<NumPins;i++) { Serial.print(N[i]); digitalWrite(N[i] + 1, LOW); delay(delayTime); digitalWrite(N[i] + 1, HIGH); delay(delayTime); } } void setup() { Serial.begin…

I think that with some adjusts it can easily do what you are looking for.
