Can i make arduino blink and still use other functions?


I wonder if i can have my robot do his stuffs and, lets say when the machine just go straight forward makes LEDs blink, like 100ms on and 100 ms off.

I thinking this must destroyed my program because i need to have delays for the other operations. Do i need to have two micro-controllers just for stuffs like this?

Please search for blink without delay.
