greenhouse project on IOT cloud with stepper motor - problem with stepper motor

Hello,

I started thi sproject where I have a green house and an arduino mkr1000, and I started to work on the IOT clound offered by arduino.
I have few sensors: two dht11 (one for inside and one for the outside).
Based on temperature and humidity I want to a small panel to open so the air can come inside from this window.
I have a nema 17 stepper motor for open and close this sliding panel and two end switched (1 for th eleft and 1 for the right) that are telling to the stepmotor when to stop.

I connect everyning but I have a small problem with the stepper motor. It si working with the sample code that that we can find in the sample folder (“stepper_onerevolution”) but with my code th stepper motor is not working, it is doing a weird noise. CAn you please look at my code and check if there is something wrong please.

const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor

// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

#define DHTTYPE DHT11

DHT dht0(DHTPIN0, DHTTYPE);

Hello,

Why is so difficult to get an answer in the arduino forum? I'm in th wrong section? or my expectation are too high?
