You have not followed the directions I gave you. Read my reply again, follow what I have told you to do and it should work.If you look at the error you are getting, it clearly shows what you need to add- which you have not done. If you look at the information I provided, I gave you both lines that you need to add and told you where to put them in your sketch. You have not done any of this. So, it appears that you are using the exact same sketch that gave you problems in the first place and expecting different results.
