Well,
i did test it with a new sketch see my first post
i know it is connected good, because when i load one of the examples sketches for the dallas temp sensor it shows, 2 sensors and displays the correct values.
after altering my sketch with the temp1 and temp2 variabels set.
it now run's oke.
But why it didn't run in the first time i don't know.
for now i'm happy that my sketch is up and running.
