Led blink without delay please help

larryd:
Proper formatting of your code makes things a lot easier to follow.

This is especially true when you review your sketches 2 years from now :wink:

Did you add a series dropping resistor to each LED. :o

220, 330 or 470 Ω

Please, in the future, supply us with information we request.

Also, follow TomGeorge's request in the previous post.

i did not add a resistor because the brightness is too low if i add a resistor
