That was an old post, Erik posted in this thread
that he is now using ServoTimer2 .
Erik, you can use the map function to scale values from 0 to 360 to the values needed by the servo library. You will need to play around with the min and max values to get the exact range you want, but the map function that returns values suitable for ServoTimer1 would be:
map( postion, 0,360, 750, 2250); // this returns pulse widths between 750 and 2250 us for inputs ranging from 0 to 360 degrees.
See the Arduino reference page for more info on map
