I don't see a ground between the mega and the stepper driver.

Welcome to the club!

http://forum.arduino.cc/index.php?topic=228284.0

I thought I could fix it by going  into the control panel (windoze) and deleting history( cookies etc.) but that did not work.

I use Chrome to see this site and one time I opened a second Chrome and I noticed it had several choices for me to pick.

In other words my history (cookies?) with Chrome was not cleared.

I went into Chrome settings and there I was able to clear out  my history and now I'm able to log on.

It looks like this might suit your needs.

If that's the code you are using then it looks like you are still not in dir /step mode of the stepper driver.

All you need is :
Code:
Stepper stepper (STEPS,8,9);  dir/step
6  Using Arduino / Programming Questions / Re: Stepper motor Potentiometer tutorial for step/dir pins on: April 06, 2014, 01:41:01 pm
Just use 2 pins in the setup not 4 . 

Don't remember which is which but it's just a simple test to see so I will leave that to you.

If it was my IP address then why am I able to post this ?  All I'm doing is just moving my connection from one computer to the other on my desk ( I do have to reset the modem  but that was the first thing I tried when I got the message).

I did send an email to the webmaster but did not hear back and that' s why I'm posting this to see what  happened.

If my IP stays the same then why does the website not give me the message on my laptop that I get on my desktop.

I still think that something was sent to the desktop one to be able to get this situation.

The OP's code looks like it was meant to drive a dc motor rather than a stepper.

To the OP - grab the stepper example and use the pins that map to your board.

Right now I'm on another computer to be able to post this message but starting about a month ago when I'm on my main  computer I have been getting this message when after I logon and try to enter the Forums.

I tried to create a new user with another email address but it did the same thing .

Does this website put something on my other computer to have this happen?
10  Using Arduino / Motors, Mechanics, and Power / Re: Can't control DIR pin on stepper driver ST-M5045 on: February 17, 2014, 12:23:15 pm
  I have pin 11 (PORTBP3) set as an input (default, no PinMode). 
11  Using Arduino / General Electronics / Re: Sensitivity of DigitalRead on: February 07, 2014, 08:44:59 pm
How Sensitive is the code Digitial Read?  I would like voltage outputs required for an input to be defined as "HIGH"

I wanted to know the same thing at one time so I took a pot and hooked up one end to the 5v  and the other end to GND and fed the middle one to both a digital input pin and an analog one and when the the digital pin read high ( or low) I would read the analog value and send it out to the serial monitor.

There is some gap between the high and low.
12  Using Arduino / Motors, Mechanics, and Power / Re: L293D And Stepper on: February 06, 2014, 08:23:30 pm
Pin 8 is for the power supply to the motor (12 volts in your case) and pin 16 is for the logic (system)supply voltage(the 5V pin on the due).

Your fritzing shows a due which is a 3.3V logic  system where an UNO is 5V.

The L293D has a minimum of about 4.5V for its logic supply voltage. So it needs the 5V from the due. It should be able to see the output from the due (3.3V) as a high.

So in your first fritzing it looks like you had the power hooked up correctly but not the others.

I would first use a known program  to test the stepper. Go  with the example programs for steppers found in the example area of the file tab.

Pin 20 on a 16 pin dip?

In the Fritzing I see no connection from pin 16 to the 5V logic supply.  I would also suggest that you take out the serial part and try hard coding the steps variable.  Get one thing working at a time.

pin 20, not pin 16, this has already been pointed out.

As groundfungus said . Also do not hook up the motor supply to pin 16.
14  Using Arduino / Motors, Mechanics, and Power / Re: Servos as live input for other servos on: February 02, 2014, 04:25:29 pm
Maybe just use a pot as the input rather than a servo.

15  Using Arduino / Motors, Mechanics, and Power / Re: Easy Driver + Stepper; no result on: February 01, 2014, 09:55:19 pm
The easydriver  already has a voltage regulator on board so connecting the arduino 5 volt to the 5 volt pin ( this pin is outputting 5 volts) of the easydriver is probably not a good idea.

Is the stepper motor powered ( are the coils being driven)? That is does it resist being turned by hand of its shaft.

If it turns freely then there is no way you will get it to step.

I would look closely where your step and dir wires go into the board and where they go into the arduino.

Having those bare wires at the board almost or actually touching each other is not too good.
