I am making a robotic arm to hold my PCB's & flip them & raise them & what not (just for fun there is no reason other then that), but I can't find any info on having the servos hooked up to the arduino along w/ an LCD screen & selector setup (IE joystick & pushbutton) so that I can choose the servo controll options.
Please help me out w/ this, I will answer questions as I best I can.
Details would be welcome.
There is plenty about servo control and there are menu libraries.
Have you looked in the Playground?

I have looked @ the playground & all I see is things about servo control w/ & w/out a knob & servo, & things about LCD screens but not about using them to controll objects, just getting them to display text.
What I am going to be using is this: Robotic Claw Pan/Tilt Bracket - ROB-10826 - SparkFun Electronics I am going to be adding a 5th servo to make the claw rotate 180 degrees. The last image is basically what I'm buildining.
What I am needing if I can get it, I'll use another route if I have to by using individual switches & potentiomiters but what I'd like to do is have an LCD screen w/ the options to change the positions of the servos. But as I stated I can't find anything that has that kind of info.
LCDs are display devices; they can't control anything.
Are you talking about touchscreens?

So your telling me that I can't have an LCD screen display what I want to do & then when it is selected the arduino triggers those actions. & no I'm not talking about a touchscreen, that's too expensive.

What things does your TV screen control?
Same idea.
Then how do I display the actions that I want done & be able to select them & have them triggered into action.
That's the clever bit that your software does.
If you look around like in the Playground, you'll find examples of menus.
Try something like Adafruit 1.8 Color TFT Shield w/microSD and Joystick [v 2] : ID 802 : $34.95 : Adafruit Industries, Unique & fun DIY electronics and kits
Forgive me for a potentially stupid question. But what is the purpose of the RW bit if the screen cant be read?
So that you can read back what has been written.
No-one said you can't read, just that they can't control anything.
I'm guessing the OP meant that his screen will display a menu and the buttons on the screen will dictate what happens next.
@the OP, the buttons on the lcd board (assuming your board has buttons, of course) are all connected to an analog pin and thru a cunning network of resistors each outputs a different voltage. You then use that voltage as read on the analog input to decide which button is pressed, and then use that fact in (for instance) a switch case with each case containing the code for what you want to happen.
