I am trying to hook up a simple circuit for a prop. I need to illuminate 3 LEDs and have them each wired so they can be turned off individually (in this case cut).
I have at my disposal:
Multicolored LEDs (red, yellow, green, etc.) With no voltage or amperage information.
Resistor multi-pack
Wires
9V battery snap on adapter
2x AA adapter
4x AA adapter
Multimeter
I have read a bit on the topic. If possible I want to have each light 'cuttable' without affecting the rest of the lights. I understand this might not be possible with one power source. I know a series would likely need to be used so they don't all go out when one is cut, but the amperage would change as some are removed, and I'm not sure if LEDs can work with those fluctuatuons.
My biggest issue at the moment is I have the LEDs without any information. Can I measure them somehow using the multimeter to get the V and A required? I have some idea how to identify the resistors and there amounts (or read them off the meter) but I can't find the right resistor without knowing the LED specs.
I imagine I would have the positive lead off the battery going to the 3 resistors which are connected to the LEDs long leg (cathode?) And then the short legs would link back to the negative terminal on the battery.
Any help would be fantastic, I can provide more information if needed. Thanks!
