Ok I have 7 0603 SMD LEDs and another set with 7 0603 LEDs, both on separate circuits. So 7 0603 SMD LEDs being lit from a 5 volt source how many ohms do I need to resist if each LED is 1/8 watts each? I used this cac: http://www.the12volt.com/ohm/page2.asp and got 28.57143 ohms how many is that? do I round it off?
So I need to know what size resistor to use for seven 0603 SMD1/8 watts (each) LEDs coming from a 5 volt source?
