Hello All.
First off I know nothing about electrics so please ignore my stupidity!
I'm making an A4 21st birthday card, and on the inside I'd like to have a showbiz style mirror with LEDs instead of lightbulbs.
I'm going to drill small holes through the plastic mirror so that the legs of the LEDs poke through but the bulbs stay on top. I'm making the card out of thick mount board and it will have an area behind the mirror to house the circuits and batteries.
My question is:- How many LEDs can I run off one 9v battery (I'd like 24 in total) and is this as simple as daisy chaining the legs together, connecting a resistor at one end and the battery at the other with a switch somewhere in between?
Thanks for reading and any help will be greatly appreciated.
