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.

// for your motor
// initialize the stepper library on pins 8 through 11:
