spacing test

  EVERY_N_SECONDS(10){  // Demo: Changing the pixel spacing every N seconds.
    Serial.print("  last spacing: "); Serial.print(spacing); Serial.print("  ");
    spacing = spacing + 1;
    if (spacing == 11) {spacing = 2;} // don't want to go past 10
    if (spacing == 6) {spacing=8;} // want to skip 6 & 7 as they don't look right
    if (spacing == 9) {spacing = 10;} // skip 9, go-to 10, do 10 then start again at 2
    Serial.print("\tnew spacing: "); Serial.println(spacing);
  }



The above gives this output in the serial monitor:
  last spacing: 2   new spacing: 3
  last spacing: 3   new spacing: 4
  last spacing: 4   new spacing: 5
  last spacing: 5   new spacing: 8
  last spacing: 8   new spacing: 10
  last spacing: 10      new spacing: 2
  last spacing: 2   new spacing: 3
  last spacing: 3   new spacing: 4
  last spacing: 4   new spacing: 5
  last spacing: 5   new spacing: 8
  last spacing: 8   new spacing: 10
  last spacing: 10      new spacing: 2
  last spacing: 2   new spacing: 3
  last spacing: 3   new spacing: 4
  last spacing: 4   new spacing: 5
  last spacing: 5   new spacing: 8
  last spacing: 8   new spacing: 10
  last spacing: 10      new spacing: 2
  last spacing: 2   new spacing: 3
  etc.
