Does a resistor get soldered to both ends of an LED or just one... Whihc one??? Thanks.<HR></BLOCKQUOTE>

If you can see through my awful freehand drawing (Photoshop isn't that friendly to use for this particular purpose, and my mouse is a bit f$&#*@&*ked up!), this ...ahem... "diagram" should make things clear.

The brown thing on the bottom is the battery.
Its (+) terminal is connected to the LED's anode, its (-) terminal is connected to one leg of the resistor, and the other leg of the resistor is connnected to the cathode of the LED.

Technically, it doesn't matter which lead of the LED you connect the resistor to, as long as it gets in there somehow.

Resistor is placed between the source and the LED. The LED is placed between the OTHER source terminal and the resistor.

I.E. all components are in series.

Of course, you could place a resistor in parallel with the LED if you have some battery power to waste
