ahh thats great, Thank you very much, my knowledge has increased greatly over the last few days.
All I need to do is work on a way (with perhaps my physics teacher) to create a test that would give a range of values that I can then graph, and find out exactly how windspeed is related to the output voltage, and then I can create from that an equation that turns the input voltage into a speed in mph (and display it) and the convert that to display a speed in knots (and display that too)... I will proberbly then have to do the same with a thermistor, and humidity sensor. the wind vane (Which ever one I deicide to use: pot/encoded shaft with phototransistors) will just be x voltage = north etc..
Cheers,
Owen
