    You can also use 12V LED strips, which have the resistors built-in. That's what I put in my PSU.

    Formula: R = (Vs - Vf) / If so... (12-3.3) / 20 = 435ohm resistor, so round up to next highest resistor available if that rating is not available. Why are you using the 12 line? You could use the 5v if you want and just recalculate with the formula…

    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…
