 **Resistors can be installed in any direction**.
-Smaller value capacitors (i.e. usually under 1 uF) generally have no polarity.  Anything above 1 uF is typically an electrolytic capacitor, and it will have a polarity marking.  Most often the "-" side is marked with a big stripe, although sometimes it's the "+" side that is marked.  (Strangely, the "+" side seems to be marked on capacitors made in U.S.A.)

 **//Diodes absolutely must be installed in the right direction//**.  Diodes have a stripe on the cathode side.
