Step 1: Collect the parts!
1: 5mm LED's (1-6)
2: 330 Ohm resistors (one for each LED)
3: 9 volt battery (1)
4: 9 volt battery adapter (1)
5: a switch (optional)
6: a project enclosure (I used an old deodorant case)
1: a soldering iron
3: a drill (or anything else that will make a 5mm hole in your project enclosure)
4: your hands
(Sorry, the picture is really blurry)
Step 3: Decorate!
I just left mine black, because I thought that it looked best like that.
Step 4: Connect!
Solder all of the negative leads on your LED's together.
(the negative lead will be shorter)
Step 5: Resistance!
Then, solder all of the resistors together, above the actual resistor!
Now, solder the negative(black) wire from the battery adapter to one of the negative LED leads.
Next, I connected the positive(red) wire from the battery adapter to one of the resistors through a flip switch, but you can use anything to connect them, you could even connect it directly, but the LED's would burn out pretty quickly...
Step 7: Drill!
I put one hole in the side of mine for the switch.
Step 8: Put it all thogether!
I put the switch in the hole that I drilled for it.
now close, put the lid on, or seal your enclosure.
