I need a hand with something.
I need to wire up 3 blue LEDs to a standard 9v battery. It must also have an inline switch.
I've tried Google but its all about LEDs wired to your computer or to your car so its a whole different ball park to what i need.
Can it be done and how? Please use basic terms as i'm not experienced with DIY electronics.
Thanks in advance

Just simple live and neutral connections aint it?. and obviously i think u will have to loop the led's together?!

then wouldn't you just need to take the LEDs and connect their wires directly to the battery? like + to + and - to -? i did something like this when i was in grade school...go science fair!

But i'd want a switch and i have also been told i'd have to put in a resistor.

what is this for? it sounds ALOT like what i did in grade school lol
take a regular light swtich and hook up the LEDs to one side...then take the battery and hook it to the other side...switch goes on, currents open and power from the battery flows to the lights?

you need to know what the input requirements are on your LED's to know if you need a resistor or anything like that.

Errr I'm so embarassed as to which way would be best to cable this .... Parallel or Serial? I think Serial. Not doing much electrical theory in a while makes you rusty
So basically here goes easy as pie:
-0-
| |
-0-
| |
-0-
| |
| |
/ |
| | + -
/ = switch

Looks simple enough to me Jdat, thanks. No resistor though? will this be ok?

I'm drawing a blank here .... what's the resistor for in this circuit? Is it supposed to lower the current load or something?

You need a resistor or it'll not work (think it might fry, or just not pull any current... hmmm I always just plugged these into microcontrollers and stuff, apart from once I think ). I can't think what vaule you'd need but basicly in the order of k ohms probebly. The better you pick the value the brighter the LED i'll be probebly. Whats this for btw?
