int WDdirection10[18] {
  // analgo, direction (the wind come from)
  0,    0,    // N
  270,  45,  // NE
  561,  90,  // E
  642,  135,  // ES
  743,  180,  // S
  814,  225,  // SW
  870,  270,  // W
  920,  315,  // WN
  987, 360, // N
};

Create an array of actual values read from the A:D converter when the thing is pointed in the desired direction.

For instance. Point the wind vane north, what id the readout for the A:D converter? That's your north reading.

Now turn the wind vane south, take AD readings, that's your A:D reading for south.

Use real world values instead of values you thing they should be.
