Even that you can hear several suggestions for this problem, the best is to
use a 7815, since it is available at the market, and prices are cheapper
than the probably 3V zenner someone would recommend.

Use the right tool for the right job, even that for a learning experience
you can try resistor voltage dividers, diodes, zeners, etc.

This kind of voltage "adapt" with 78XX regulators is used when you need a
voltage not available directly from those kind of devices.  But for 5, 6,
9, 12, 15V, etc, nothing better than use the correct regulator.  What other
simply and easy solution you may have for less than 1 dollar?
