Alright, so I'm trying to build an ultraviolet LED light. I have the parts and everything, but I'm still new to a lot of this stuff. I used an LED calculation wizard to figure out what kind/how many resistors I would need for the array I wanted to build and it came up with this...
+----|>|----|>|---/\/\/----+ R = 150 ohms
+----|>|----|>|---/\/\/----+ R = 150 ohms
+----|>|----|>|---/\/\/----+ R = 150 ohms
I'm running 6 LEDs at 3.3v forward voltage and 20mA with a 9 volt battery. Now, the part I'm unsure about with the solution is where everything gets soldered. I think that it looks like I'd have to solder the 3 resistors all together to the negative end of the 9v battery and then 3 positive sides of the LEDs to the positive side of the 9v. Basically, I'm just having trouble understanding the diagram so any help would be appreciated.
