Stepper wont work with Mysensors



  • Hello,

    I try to run a stepper 28byj-48 with driver in mysensors. As soon as I Mysensors.h activate the stepper motor will not run. Can anyone help me what I do wrong. I use Int 4,5,6,7, above. Also at 3,4,5,6 not work I put too // for Mysensors the engine is running normally. Also burn without Mysensors all 4 LEDs. With Mysensors burn only 3 LEDs.



  • Hi,
    we need

    • Schematic
    • Code
    • Relevant links to the used parts i.e. datasheets


  • Here the image and the code that i wil use it a start. I am new to programm arduino.

    Schematic that i use this works without Mysensors.h (see the sketch)

    Sorry i can get the  code not in a nice black box.


  • Code looks good so far... (you misplaced the starting and ending ``` to mark code in a black box).

    What I can tell you from own, painful experience: If anything fails with the radio setup (also registration I think), loop() will never be executed. I was testing a LED library, working perfectly without MySensors.h but not doing anything with MySensors.h included.

    Later I realized my controller was switched off..after I switched it on everything worked. So ensure that MySensors can communicate properly. That means implementing presentation() and all other functions..



  • @Pansen,

    Thanks i give it a try.



  • @ Pansen It work now!
    When connect the radio then the 4e led and stepper is working.
    Thanks for the help.
