Yes am I am using a resistor (it is on a breadboard).
What I meant is that after implementing the other suggestions of adding () which I had neglected to do after the function calls the flashing is working fine. I was just trying to explain that the delay values I am using give me distinct flashing patterns. I still need to play around with the different delays to get a proper S O S signal.
The original tutorial that I was trying to change was from the book "30 Arduino Projects for the Evil Genius". I was just trying to point out that the delays used from that tutorial were giving me distinct flash patterns.
I have played around with different values and have found that anything down to about 50 miliseconds gives me a flashing effect.
Cheers
