Program for Stepper Home positioning

Using Arduino Programming Questions
#1

I want to set a Home position for a stepper. I already have a Hall effect sensor and a magnet, I just need the code that will make the stepper rotate until it reads the '1' from the sensor. Can somebody help me please, i'am a bit lost.

#2

Would it be something like:

if(pushbutton = High){ do{ //stepper moves 1 step// }

while(Sensor=0); }

?

#3

Have you tried experimenting in the Arduino IDE?

This isn't the whole code but it is the logic.

while(sensorVal != 1)
{
//update sensorVal with a read
//have the motor move a step
}
