integrate a piece of code for a stepper motor

[diepie]

In the Sinric Switch sample code ( switch_example.ino -> https://github.com/kakopappa/sinric/blob/master/arduino_examples/switch_example.ino ) I have to integrate a piece of code for a stepper motor that needs to loop, after device ID 1 is true, so after this line:

void turnOn(String deviceId) { if (deviceId == "5cf8de1d0837cc3a87c8faf5") // Device ID of first device

This Is The piece of code that has to loop:

void loop() {

//Change direction when the stepper reaches the target position if (stepper1.distanceToGo() == 0) { stepper1.moveTo(-stepper1.currentPosition()); } stepper1.run(); }

Question Is Where do I have to put this peace of code so that it loops, i cannot have to instances of void loop()

Regards Peter

what are trying to do ? turn on the stepper motor? You can't have a loop inside void turnOn(String deviceId) ...

I dont understand what are you tyring to do here. So i am going to guess based on a command you receive, you are trying to move the stepper

bool moveStepper = false;

void turnOn(String deviceId) { if (deviceId == "5cf8de1d0837cc3a87c8faf5") // Device ID of first device { moveStepper = true; } }

void loop() { .... if(moveStepper == true) { moveStepper = false;

if (stepper1.distanceToGo() == 0) { stepper1.moveTo(-stepper1.currentPosition()); }

} stepper1.run(); } }

thanks, i'm going to try and come back to it soon

The complete code with your proposal is pasted below. The problem is still that the piece of code that the stepper motor has to run is only executed once when it is switched on. This code must loop until the current Position is reached

Hi, without reading your whole code... Remove "moveStepper = false;" after "if(moveStepper == true) {" and put it in an if statement that only gets executed after the posisition is reached. The loop will run until "moveStepper" is false, so don't set it to false if you want to move the stepper further.

This really has nothing to do with sinric though, it's simple arduino programming, you would be better of posting this in an arduino forum.
