I'm trying to install some LEDs in my ps2 and I don't know much about electricity. This is what I did (look at attachment), I solder a negative wire to the black dot and the positive I soldered to the red dot.
Is this the right setup to get power for the LEDs?
Also what is the ground for?
Sorry about the newbie questions but, like I said I don't know much about it.
Thanks in advance. ^_^
