AWOL:
You have put "delay(0020)" which delays for 20ms not 200ms. S
Nope, read it again.
What AWOL is getting to is if you precede a numeric value with a zero the compiler will interpret the rest of the digits as an octal value. So, 0020 would be interpreted as octal 020. Octal 20 converts to decimal 16. 16ms between the short blinks on is still too fast to differentiate the two blinks from each other.
