THE CODE
The code we are using does not require any libraries, but you could use one to control the Stepper motor to give you more options if you want.
#define step_pin 9 // Pin 9 connected to Steps pin on EasyDriver
#define dir_pin 8 // Pin 8 connected to Direction pin
#define MS1 10 // Pin 10 connected to MS1 pin
#define MS2 11 // Pin 11 connected to MS2 pin
#define SLEEP 12 // Pin 12 connected to SLEEP pin
#define X_pin A0 // Pin A0 connected to joystick x axis
#define Joy_switch 4 // Pin 4 connected to joystick switch
#define Limit01 2 // Pin 2 connected to Limit switch out
#define Limit02 3 // Pin 3 connected to Limit switch out
int step_speed = 10; // Speed of Stepper motor (higher = slower)
