Hey guys, I was wondering what kind of resistor to use if I'm using 2 blue 0603 led's. I tried this resistor calculator but i didn't know mow much volts it needed or the current( mA i think?) And I read it was 10 ohm resistor, but I thought that was kinda low.
Also, I was about to order some soldering flux, then I stumbled upon some soldering paste. So I'm not sure on which one to buy. Which ones better for smd soldering? Whats the difference?
