WHAT IS WRONG ?

#2

Where is the end of your loop() function?

#3

aarg:

I've already corrected everything, thank you.

#4

In future, use menu → tools → autoformat inthre the IDE to indent your code properly. That way it’s easy to find mismatches in curlies ( ‘{’ and ‘}’ ).

Also post your code using code tags.

Lastly this might or might not do what you expect

if(aDuracao<(media*TOLERANCIA))
      aDuracao=media;
      aDuracao=aDuracao/58.4 ;
