I greatly appreciate the help from my other two arduino questions.
But I have another one,
basically with my wavemaker using potentiometers won't work since there are many parameters(pump revup speed, time for the rev up,
on lengh when PWM peak has hit, rev down speed, rev down length and pulses per minute) that need to be tweaked to make a literal wave that's highly desirable for a reef aquarium and much too expensive for somebody who is 17
Plus I love dealing with arduino!
My current thought is using a Nintendo DS touch screen since they are cheap and not that hard to get working, since people have used them many times before.
This is probably a drop shipper or a guy who bought a thousand of them,
but do you think it's too cheap, even if I bought 3 or them?
It's just the touch screen right ?
So I need to find a harder to find TFT LCD to go under the screen that's for the DS?
I know the touchscreen is compatible but is the DS's LCD screen?
I kind of recommend you buy from sparkfun(http://www.sparkfun.com/commerce/product_info.php?products_id=8977) instead of that, they can be overly cheap, and low quality, or even fake rip-offs.
And the breakout connector too(http://www.sparkfun.com/commerce/product_info.php?products_id=9170)
To use it, it is rather easy, Just connect the X1 and Y1 to 5V(need pull-down resistor) or Ground(need pull-up resistor) and X2 and Y2 to analog 0 and 1(or any analog pin) and measure the resistance, and then map the 0-1023 value to 640X640(or whatever for X and Y)
You could order this unit from Dealextreme: http://www.dealextreme.com/details.dx/sku.3245
dealextreme has a reasonable reputation. And I like their policy/feature of having per-product reviews. You can get a lot of useful info from those...
Okay that answers my question.
What do I use for a LCD that has been proven to work with the arduino without too much work ?
I'm not trying to be lazy, I'm just not that knowledgeable
Umm...I am not too sure, I know it is possible, but you need to go through allot of hassle, and it's not cheap...
But you can put a printed paper behind the touchscreen, Instead of getting an LCD to display a still image, but if you want more, then go with the LCD.
You can interface with the LCD using the Arduino KS0108 Graphics LCD libraray. Note that the circuit-ed LCD is not pin out placement compatable to the examples in the KS0108 library. So you have to make your own breakout board (so to speak). Also there is no touch screen library so you have to write your own. I was able to get the display working and the TS input working SEPARETLY but when I last combined my code (into 1 single sketch) it was buggy. Haven't looked at it in over 3 months but I will get back to it. Anyway, hope this info may help you.
Well since I'm not making this into a product to sell or anything.
I think I will do a touchscreen and paper(nicely)
and have 1 16X4 generic LCD that's supported without a doubt.
Sometime maybe I'd do a real LCD and touch screen,
but for now I just want some functionality with spending money and spending lots of time
I'm not too sure about that, You could use A few of those Low power 5V relays to be used directly with the arduino.
But you're probably better off starting a new thread about it.
