hi, ì`m trying to figure out how to use leds with an arcade power supply, but the leds just support 20mA and the lowest current from the PSU is 2,5A from 12V. How could i find a resistor good enough to low both current and tension to 3,3v and 20mA? I can`t figure out a way to low the current to that. Besides, i`m trying to use 3 leds. I must associate them in parallel to maintain the same voltage that i need(3,3v), isn`t it?
