AH HA!
I love it when I'm right!
now all i need is the sparkfun delivery to arrive, and a 1 10KOhm resistor and I can have a play with the wiring :S
there is some sample code I am going to base my work on (why reinvent the wheel?)
and has the following wiring diagram
+5V

> 10K
< Resistor

Analog Pin 5-----|

-------| To weather vane

am i right in thinking, i can take a feed from the 5+v pin on the arduino, put my resistor in line, then split the line one going to pin 5 (or my chosen pin) and the other to the weather vane.
and GND just goes direct to the Arduino GND pin?
if so, can someone explain how/why this works? so that I understand please?
