need help taking one LED from RGB 5050 strip, also remote and voltage questions Answered
So I have an RGB 5050 LED strip. It's cutable every three lights. I need just one LED. So I'm figuring (correct me if I'm wrong, because I'm a total newbie to this) that I need to solder the 3 pins on one side together, and put a resistor on each of the other pins (with the red getting the resistor that's a different value). Problem is, I don't know which pins are which. There's a little mark on the corner of the LEDs; do I put the resistors on this side, or the other side?
This strip is meant to be used with 12 volts. Also pictured is a remote with receiver and a mini controller (I will use one or the other). These are also for 12 volts. I'd like to use them with less. I tested with a 9 volt battery, and that worked. 3 volts did not work, not sure why. I haven't yet tried 6 volts. Is there anything about the controllers that requires more voltage, or is it an issue with the LEDs? I do not have any specs on the LED strip, but don't pretty much all LEDs work with a 3 volt coin cell? Since the resistors were being used for all three LEDs, how does it impact things when I switch to just one LED?
I also took apart an LED candle that has a similar remote, and it was also meant to run on 12 volts. It works perfectly on 3. I would just use this, but sadly its round shape doesn't fit.
Any help is very much appreciated. Thanks.
edit: Just tested with the remotes, 3 LED strip, and 6 volts, and only the red LED works.
