recipe for LED salad

[LED salad]

Hi, I've got to do a project that has to consist of the following items listed below. Please advise how to go about getting it together.

1 x red LED
1 x yellow LED
1 x white LED
1 x light orange LED
1 x dark orange LED
1 x 3.8v 0.3A torch globe
Resistors
Power supply
Switches

It has to be connected in the following way:
Red and yellow LEDs in series
Light orange and dark orange LEDs in parallel
The clear LED and the torch bulb connected together .
- the correct resistors to be connected where necessary
- all of the above to an adequate battery power supply
- all of the above controlled by a single switch.

Please advise AS SOON AS POSSIBLE in detail and in simple step by step guide as to how to get the required outcome. Or by means of a simple diagram.

Wow, you don't want much, do you? Is this school homework?

First I'd choose specific LED's and torch globe.

Then I'd draw it out (I'm not sure what "The clear LED and the torch bulb connected together" means). You'll want a current limiting resistor for each string of series LED's.

After that look at the drop of each LED and figure out what voltage you want the power supply to produce (probably higher than the greatest drop in a series group).

Now you can calculate the value of each resistor.

Hey Steve, you missed a trick there!!
He knows what to connect to what, how to connect them!!
Mums coming to check homework in five minutes!!....
You just lost your Xbox for a week...

Note to self...Don't leave homework until last minute.

Never connect LEDs in parallel.

Never connect LEDs in parallel.

Not without individual resistors, anyway.
