Hi, I am brand new to Arduino and have a Arduino uno. I found a YouTube video with the code of what I want the unit to do and I uploaded it to it but it is not working properly. All I want is for the Arduino to turn the stepper motor one 360degree rotation clockwise at the push of a button and stop. I want this to only happen every time I push the button, but the unit is turning on every 30 second’s automatically and rotating for exactly 38 seconds and stopping. I don’t want this to happen. I’ve spent days trying to remove lines of code and change things to stop this from happening but I can’t figure it out. Also, don’t even need the code to move the motor counter clockwise, if anyone could help me edit out the second button altogether.
Here is the code:
int Pin1 = 10;//IN1 is connected to 10
int Pin2 = 11;//IN2 is connected to 11
int Pin3 = 12;//IN3 is connected to 12
int Pin4 = 13;//IN4 is connected to 13
int switchCW =2;//define input pin for CW push button
int switchCCW =3;//define input pin for CCW push button
int speedFactor =1;//1=fastest, 2=slower or 3 more slower
int correction_CW = 150;
int correction_CCW = 150;
const int CW =1;
const int CCW =2;
const int STOP =3;
int poleStep = 0;
const int SPR=64*64;
int pole1[] ={0,0,0,0, 0,1,1,1, 0};//pole1, 8 step values
int pole2[] ={0,0,0,1, 1,1,0,0, 0};//pole2, 8 step values
int pole3[] ={0,1,1,1, 0,0,0,0, 0};//pole3, 8 step values
int pole4[] ={1,1,0,0, 0,0,0,1, 0};//pole4, 8 step values
int count=0;
int dirStatus = STOP;// stores direction status 3= stop (do not change)
void setup()

Serial.begin("Robojax Video for Stepper Motor STPB-2");
pinMode(Pin1, OUTPUT);//define pin for ULN2003 in1
pinMode(Pin2, OUTPUT);//define pin for ULN2003 in2
pinMode(Pin3, OUTPUT);//define pin for ULN2003 in3
pinMode(Pin4, OUTPUT);//define pin for ULN2003 in4
pinMode(switchCW,INPUT_PULLUP);
pinMode(switchCCW,INPUT_PULLUP);
