Hi everyone,
I just have a quick question about the placement of resistors. Do they go in front of LED or after?
Such as:
VCC+=>R1=>LED=>GND
or
VCC+=>LED=>R1=>GND

Your choice... makes no diffs

Doesn't matter. Current anywhere in a series circuit is the same.
To light up 10 LEDs one at a time using Digital Pins, I can either use 10 Resisters before the LEDs, or a single Resister just before the ground commonly? Makes no difference?

No, nobody said that. Ten LEDs need ten resistors, regardless. You should experiment and see for yourself what happens when you use one resistor for two or three LEDs.
Common resistor is ok as long as only 1 LED at a time will be on.
Brightness will vary if you start driving more than 1 with a common resistor.
