24 LED strip
I've got what i thought would be a simple project so i could take some impressive long exposure photos.
Heres the materials i have: (also see pic)
1: 24 white led's soldered in series (yes i started without knowing what i was doing :P )
2: A small 4.5v battery pack.
3: A simple clicky switch.
Heres what i dont have:
1: A clue about resistors or where to add them.
2: I don't know what voltage the leds are as they were removed from a broken led lamp by my brother. (who also dumped the casing so i cant see what the circuit on it looked like)
3: Any more patience. :)
The third pic just shows one of the 24 leds being tested with a 3v battery. I've done this with all 24 to make sure that there are no dead ones.
Can anyone help my ignorance?
