Why do you load titres.txt on each function? Declare the array globally and load it in setup().Note that you should call size() at the start of setup(), even with a dummy size. Not sure if it changes...

Thank you for your reply ! I load titres.txt on each function because when I declare the array globally, I get this error :The file "titres.txt" is missing or inaccessible, make sure the URL is valid...

You don't necessarily need a constructor. You can always call the default constructor, which has no parameters, likeScore score = new Score();If you just write Score score;and want access variables of...

yes, but the problem is that the string myString is not always long the same as it should bean example of correct string is 12345:100:1the first number, 12345 is the time in the function millis()the...

hehe and welcome to the world of debugging. So a collision makes the score go up? Check if the collision works correctly.Is there something else changing the Score? Consider that everytime you create...

Yes! you can! first send only a byte. If work good then try to send two bytes or three with all your paremeters...Is better control your data only with a bytes....no with strings... if you use...

ehm really no...i don't understand how I can send bytes instead of a string. Do you mean to convert it to a binary code and send only 0 and 1?The Arduino program has no errors; it is only four lines of...
