yes I know this is an error but I wanted to read the value from pin 4. this example worked for me (RelayActuator) I wanted to use this ordinary switch to control the rest of the program. that's all I need at the moment

I would like to use this program in mysensors with a switch from domoticz

#include <Stepper.h>
#define STEPS 32 
Stepper stepper (STEPS, 8, 10, 9, 11); 
int val = 0;

void setup () { 
  Serial.begin (9600);
 stepper.setSpeed (800); 
  pinMode(4, INPUT_PULLUP); 

}

void loop () {
  if (digitalRead (4) == LOW) 
  { 
    val = 20480; 
    stepper.step (val); 
    Serial.println (val); 
  }
  
 if (digitalRead (4) == HIGH) 
  {
    val = -20480; 
    stepper.step (val); 
    Serial.println (val); 
}
}

@scalz said in Mysensor usb gateway serial problem:

If it doesn't help, like mfalkvidd said please show us your debug logs.

OK i do //#define MY_RADIO_RF24 because for now I wanted to make a base station via usb

I will tell you my idea and you will tell if it is possible here because I am slowly losing faith XD
I want to use mega2560 to control several devices. One of them is the roller blind that I converted into electric motor control (currently I have two. The first classic 2 wires and I have connected to 3 contactors which control the direction and time of operation. The second stepper motor).
I now want to use my sensor to control the blind in domoticz with 1 switch or if it could be slider.

The next thing would be INA219 but maybe later for the time being on this roller blind, is it possible to do?

Hello, could somebody help me and say why it doesn't work?
