[Lab] Roll call for tonight's modlab ...

[Darcy Whyte]

I'm going to be floating around. I'm bringing a case of water.

And a drawbot. Anybody want to have a whirl at tweaking the program?

It's pretty simple. It uses the random function to come up with motor turns
and then tries to stay on the page using some upper and lower bounds.



#include <AFMotor.h>

AF_Stepper motor(48, 1);
AF_Stepper motor2(48, 2);

void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps
  Serial.println("Stepper test!");


  motor.setSpeed(280);  // 10 rpm
  motor2.setSpeed(280);
 // motor.setSpeed(280);  // 10 rpm
 // motor2.setSpeed(280);
}

int x=0;
int y=0;

int xBound = 1000;
int yBound = 1000;

int dx;
int dy;
int xd;
int yd;

void loop() {

 dx = random (0,500);
 dy = 1000-dx + random (0, 100);
 //dy = random (0,500);
 xd = random (0, 100);
 yd = random (0, 100);
// xd = 1;
 //yd = 1;

 if (xd > 50) {
   if (x <= xBound) {
     motor.step(dx, FORWARD, INTERLEAVE);
     x = x + dx;
   } else {

   }
 } else {
   if (x >= -xBound) {
     motor.step(dx, BACKWARD, INTERLEAVE);
     x = x - dx;
   } else {

   }
 }
 if (yd > 50) {
   if (y <= yBound) {
     motor2.step(dy, FORWARD, INTERLEAVE);
     y = y + dy;
   } else {

   }
 } else {
   if (y >= -yBound) {
     motor2.step(dy, BACKWARD, INTERLEAVE);
     y = y - dy;
   } else {

   }
 }

  //motor.step(1500, BACKWARD, INTERLEAVE);
  //motor2.step(1500, BACKWARD, INTERLEAVE);


}


  //Serial.println("Single coil steps");
  //motor.step(10000, FORWARD, SINGLE);
  //motor.step(100, BACKWARD, SINGLE);

  //Serial.println("Double coil steps");
  //motor.step(10000, FORWARD, DOUBLE);
  //motor.step(100, BACKWARD, DOUBLE);

  //Serial.println("Interleave coil steps");

  //#ifdef MICROSTEPPING
//  Serial.println("Micrsostep steps");
//  motor.step(100, FORWARD, MICROSTEP);
//  motor.step(100, BACKWARD, MICROSTEP);
//#endif
