@Mike.. haha, good catch.. don't mind me.. I don't think too much before I post, if you haven't noticed.
@ABC, there's nothing wrong with asking for help..... but when you ask in the same forum, in 4 different areas of the forum.... it's a bit annoying. Especially if I was to answer it here, then in another post (like Grumpy just did not too long ago)... we say basically the same thing.. you're just wasting peoples time now.
Well I don't understand.. if you can build a small wifi car with the Arduino.. how are you having problems with something semi-simple like this? Unless, of course.. you just used somebody elses setup, code.. etc..
But anyways.. you're almost there.. if you got the LED on.. then you're halfway there, try experimenting some.
