Hello, newbie here,
I've got a small project involving LEDs, and need help finding the right resistor/battery combo. If this has been asked before or there is a good thread already explaining this concept, please let me know.
I need to wire 2 LEDs in parallel, each with their own switch so they can be turned on independently from each other. The LEDs I will be using are here.
The problem is that I don't know which resistor to use with it.
I would like the circuit to be powered by a AA, AAA, 9V or similar household battery.
If you could explain what level resistor to use with what battery (and maybe post a link of the resistor from this electronics store) I would be very grateful. Also if you could explain in your response how you got to the answer (V=IR and all that) that would be great.
Thanks in advance
