'MySensors' does not name a type



  • hello, i'm new in arduino and in das forum
    and i have this error in code
    i hope they can help me.
    /////////error//////////////
    exit status 1
    'MySensors' does not name a type

  • 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


  • Mod

    @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/
