hello, i'm new in arduino and in das forum
and i have this error in code
i hope they can help me.
/////////error//////////////

Maybe post the code so that people can see what is wrong with your code

This line is not necessary in MYS 2.0

@Sander-Stolk
o thank you, i will prove without that line

@adrian_kbb73 Welcome to the MySensors commu ity!

Most of this code seems to be for MySensors 1.x. It needs to be converted to work with 2.x. A guide is available at https://forum.mysensors.org/topic/4276/converting-a-sketch-from-1-5-x-to-2-0-x/
