Im not exactly sure if this is even possible, but I would like to connect my arduino Mega to an old computer LCD screen (http://cgi.ebay.com/LCD-SCREEN-IBM-47L7440-05264P-14-1-MATTE-/110585463699). My intention is to make a trip computer for my car to display the speed, trip miles and possibly what song is playing on my mp3 player. I looked all over the internet and couldn't find any topic about someone attempting this. I am not looking for some exceptional quality or anything, even if I could get some objects drawn on the screen I would be happy.
Thank you for the quick replys, So I guess my best bet would be to use a graphic lcd. Any suggestions on which one would work the best? I am a little confused on the difference between the serial and parallel graphic lcd screens. Would this screen work well with the arduino?
The mp3car folks are doing a wide variety of projects. So many it can be hard to find info on what you're interested in. But postings in their forum turn up often when googling for information on anything related to putting PC capabilities on wheels.
The MPG project could be a good starting point for getting trip data out of your vehicle. By using a larger LCD and adding some code to interface to your MP3 system, you could use the Arduino as your "multifunction display".
If you really want a big display, I've got some Stylistic 1200s I bought for a project a few years ago. It was a really clever idea, combining a big-screen GPS display with an MP3/ogg player, that could even function as a lightweight PC to check email and such while stopped at a wifi hotspot. Unfortunately, in a brilliant bit of timing, I got the prototype ready at just about the time they started giving away talking touchscreen GPSes in happy meals and selling smartphones with built-in MP3 and more CPU power and better connectivity than my first GUI PC
I also have some of the port expanders that make it really easy to mount them in a car (or even on a wall).
