I made a arduino and lego based steering wheel.
Pics: Sry quality, phone.

And a crappy 3GP vid i made:
DOWNLAOD IT, Better explaned idea
Sry my english, im spanish and im only 13 hehe
EDIT: I forgot, That thing over the arduino is my Shield
Colorful design 
What do you do with it ?
p.s. please don't post such HUGE images. I couldn't see all of it on my screen, and I'm already at 1280x1024. I think 800x600 is a good choice, and you can always post closeups of fine details if need be.
Sorry, i changed the img tag by url.
Ok, i got a question. The unique thing that this do is sending a 17 to 168 DEC value to the com port. Does anyone how to create a vitual joystick with VB and use this to Steer?
I only use for learning some C and Electronics. But i want to use with rFactor or something else.

int ledPin = 13; //lol
int val = 0; //Potentiometer Value
int pv = 2; // 1 for program 1 and 2 for program 2 (omg obviously)
int larr[5]={123,11,8,10,12}; //123 not used, 11 is the first led pin, 12 is the last led pin. my pins are: 11-8-10-12

pinMode(ledPin, OUTPUT);

BTW if u want some pics of my shield, only say it, and i will post some pics. No schematics available.
Comments still being allowed .__.
This would be a slightly different approach you could consider:
