Would be great if you could:

  • Open up the sketch in the IDE

  • Select Edit -> Select All

  • Select Edit -> Copy for Forum

  • Then return here -> start a new reply -> enter ctrl+V to paste your sketch in the correct format - then click "reply"

That way we'll be able to see the error and help you.

Every sketch must have a setup and loop function, that particular error is caused by not having a loop function. The loop function does not need to contain any code.
