hey. for v-day I wanna make an led heart with a on off switch. I bought some LEDs about 15 and wiring and a 9v battery. I know im prob burnign out the led instantly because when i attach it to the battery it flashes then doesnt relight. am i burning it out? and how can i prevent this?
I am using a 9v battery
a rated 300 volts, 20 gauge stranded wire.
and a SPST Momentary Submini Pushbutton Switch at 0.5A at 125VAC/250/VAC
I wanna light up about 15 red LED's
idk what to do. i didnt use a resistor or capacitor because idk what those really are (new to LEDs)
and i dont want to chain together them all incase it blows all of them.
the LED's are rated at 2 - 3 V, 10-20 mA leds (it is these http://www.radioshack.com/product/in...d...
any help? I think I just need a way to stop the battery from over powering the LEDs? and control the power? idk :/

Additional Details
ok i understand i can add more. but how many? I dont wanna blow it but is it possible to do to many?

so also say each led is 3v and the battery is 9. does that mean 3 LEDs?
so if i had a 24v power does that mean 8LEDs?
I just want to power about 15LED's and have a on off switch. thanks
