several sketchs in the same project


I'm coding a simple sketch: setup() { // blah blah blah }

loop() { //blah blah blah }

But this sketch calls big functions. I can put these functions at the beginning of the sketch, but the sketch is quite long

=> Is there a way to create another file .pde or .c or whatesover besides the .pde sketch that contains all my long functions ?

I know there's the solution to create a lib, but except using this technique of creating lib, is there another simple technique ?

See if this answers your question: :)

Thanks !!
