Hi guys,
I need to make a 14 leds circuit with a 9v battery, the problem is that i only have 220 ohm resistor, and i can't find 120 ones in my city now :(
is there a way to build this thing with 220 ohm resistor?
led are ultra blue f3 3.0 - 3.4V 20mA
EDIT: I did the circuit with 7 leds at the end, just for simplify things. and as you said the 220 ohm resistors for every led looks great and works! thank you
