I need to add to this sketch a keypad so I can enter a number to change the value of the int numShootMoveLR=4; and the int numShootMoveUp=1; before pressing the start button to run the sketch.
Can someone modify my sketch for me for a very reasonable price? I am a newbie and have been struggling with this part. Thanks.
for (int j=1;j<=numShootMoveLR; j=j+1){
lcd.clear(); //clears the lcd
lcd.print("TAKING PHOTO"); //alerts camera is shooting
digitalWrite(cameraFirePin, HIGH); //fires camera shutter through relay board
delay(3000);
digitalWrite(cameraFirePin, LOW); //de-powers relay board
delay(3000);
lcd.clear(); //clears the lcd
lcd.print("MOVING TO NEXT"); //alerts camera is moving
myStepperMOVINGLeft.step(25000); // MOVINGs table to left
lcd.clear(); //clears the lcd
}
Why do you need to clear the LCD at the start AND end of the loop?
Which pins have you connected the keypad too?
Reading the keypad, and storing the keys, and converting the stored data to an int, when the appropriate event happens (undefined), is trivial.
What event should indicate that the move LR value is complete? What event should indicate that the move Up value is complete? What event should indicate that you made a mistake entering the previous digit? What event should indicate that the whole collection of digits is rubbish and should be discarded?

I have not connected yet. I realize I will need more pins so have on order a Audrino MEGA

I don't understand what you mean
What event should indicate that the move LR value is complete?
When it fires the camera.
What event should indicate that the move Up value is complete?When it fires the camera

Notice that last sentence. Spaces indicate the end of words. Periods indicate the end of sentences.
Suppose that you want to enter 14 as the value for numShootMoveLR and 20 as the value for numShootMoveUp. Let me ask again. What event will occur in the sequence of pressing the '1' key, pressing the '4' key, pressing the '2' key, and pressing the '0' key that indicates that the characters '1' and '4' are to be used to create the value 14, and to store the value of 14 in the variable numShootMoveLR?
Typically, there would be some enter key, some backspace key, and some "oops, start over" key.
You might not need a "oops, start over" key, since you just backspace more than once.If you are entering much larger values, and notice that you entered the first character wrong 27 digits into the number, backspacing 27 times is annoying. But, if you are planning a maximum of 3 digit numbers, backspacing 3 times is not so bad.
The "use the entered digits" event then might be pressing the '#' key. The backspace event might be the '.' key.
What event should indicate that the move LR value is complete?
When it fires the camera.
When what fires the camera? Pressing the switch to start moving the camera/taking pictures as the event to indicate that the collection of keys is now to be used for making the value for numShootMoveLR is a bad idea, since you then have no opportunity to enter characters for the numShootMoveUp value.

The same event can not indicate that the collection of key values is to be used for two different purposes.
The next question, then, is what should happen if the start switch is pressed before the '#' key is pressed the second time. Should it be ignored? Or should the partially entered data be discarded, and the default values used?
