[dorkbotmtl-infusion] i want a joystick

[Elie Zananiri]

hey what's up dorkbot,

i need to build a joystick, and i was wondering if it's possible to  
do so using some sort of 2d potentiometer.  i managed to make one  
with 4 push-buttons (one per direction) but this is going to take up  
too many pins which i need for other things.  i just saw this picture  
and it looks like that's exactly what i need: http://www.arduino.cc/ 
en/uploads/Tutorial/joy_pic_480.jpg

so, anyone know where i can find this? what it's called?

if not, anyone have any ideas on how to build something like this?   
how can i use 1 stick to control 2 pots in different directions?  i  
just can't picture it...

thanks,

Elie Zananiri
