First of all, DON'T hijack threads!

Next, sure, show us your code and tell where you're stuck. "Does not work" is NOT a problem description!

And a pro tip, just like the compiler we're a lot happier with the right syntax :wink: Aka, try to separate sentences with a period (.) and a Capital :wink:

@Murphy1992, please do not cross-post. Posts smashed together.

Ahhh, fantastic job! Cross post AND hijack!

And any reason to store something extremely trivial like that on a SD-card??

the structure of the code is simple, right ?

while file is not empty
   read a line from file
   print the line to Serial
   wait for button press (and decide if you want to wait for release)

So you have 4 functions to write

  • fileisnotempty()
  • readalinefromfile()
  • printthelinetoSerial()
  • waitforbuttonpress()
