Leds Lamp
Do i need a resistor to make a lamp out of a few leds?
ok. I am going to make a lamp out of a bottle,some leds,AA battery slot and some broken glass. my question is do i need a resistor to make this.
P.S please make it easy to understand or send a pic! i am only 14!!!
It is a good idea to use a resistor because it protects the led from excessive current:

And here are some good photos of how to put the resistor in:

Also, consider using a breadboard to put your stuff together:

Breadboards let you put your components together to see how they work before you solder them. It saves time and can help you think out some issues before you get everything squared away.
