LED Question for school

[cobainlives_05]

At school some of my friends are building a model house, and a very big on for an architural class.  And with my abilty to solder and knowledge of how to build a stomp box the teacher wants me to wire the house and use leds as lights.  Here is the list of things,

-Switches on the side(not inside the house), what type do I use and would it be possible to wire each room on a different switch?

-What value leds?

-What color led is the clearest?

-Is it possible to run all this on a 6V battery if yes or now, explain.

Please tell me if these are possible, not possible, or what value and type.  All help is appriciated.

Led's have really come a long way. You can get led's that are anywhere from dull to super bright. Your best bet would be to get one of the brighter ones and use a reflector. As far as switching, leds don't use much current, so you could use just about any types of switches. Just make sure to find out how much current they will need, and use appropriate current limiting resistors.



Edit: Oh, and you'll probably want white or yellow leds.

yea, white LEDs would probably look the nicest, although they'll cost the most, probably around $3 each, compared to about twenty cents for other colors.  i think a row of toggle switches might be the best way to do switching.  I would wire SPST switches, in paralell to eachother to a battery, a resistor in series with teh switch, then all the LEDs for a room in series, and then back to the battery.

Could you draw a layout of that?  for example use 3 rooms(acually more in real house) with 3 switches, one for each room.  All connected to one battery.  I work better with a plan and not just start wiring stuff up.

Thanks, Ryan

but in three words... REMEMBER THE RESISTOR!

cool, im planing out all the parts i need now.

Try an ultra-bright blue led for the bug zapper in the back yard, with maybe a piezo buzzer or small speaker to produce the noise.
