**When a relay coil is de-energized a "back EMF" can be created. This is a high voltage spike that travels back through your relay signalling electronics, in our case our Arduinos. This can fry the electronics. A Flyback is place across the lines to suppress the spike. http://en.wikipedia.org/wiki/Flyback_diode

**A useful mnemonic matches the first letter of the color code, by order of increasing magnitude. Here is one that includes tolerance codes gold, silver, and none:
***Bad beer rots our young guts but vodka goes well get some now.
***The colors are sorted in the order of the visible light spectrum: red (2), orange (3), yellow (4), green (5), blue (6), violet (7). Black (0) has no energy, brown (1) has a little more, white (9) has everything and grey (8) is like white, but less intense.[8] from wikipedia..
