Lets see first you will need to know the max ammount of current that
the LED can operate then depending on that current and the voltage(ex 2
AA = 3v) you are going to use calculate the resistance needed in the
circuit using ohms law where R=V/I then conect the positive of the
battery to a switch so you can turn it on and off then conectt it to
the resistor then to the LED then to the negative of the battery
i guess that would be all

Hi
I need some advice on how to go about lighting up a picture made from
stained glass. The frame is approximately 24" x 24" (600mm x 600mm) and the
actual glass is 20" x 20" (500mm x 500mm)
I want to make up a frame approx. 1" (25mm) thick to sit behind the picture
frame. Within this I want to insert some white LED's to light the picture
from behind.
I need help on how many I would need, where would be the best place to
source what I need (in the UK), what I will need (LED, resistors
transformers?) and some ideas on mounting the LED's. Also, what sort of life
would I get from batteries, maybe a couple of AA ones? I'd hate to have to
start channelling walls to run power to it!
Lots of questions but I would appreciate any help.
TJ
