Hey, I want to make a get better poster with led light sticking out of the poster. I found the following LEDs: http://www.play-zone.ch/de/bauteile/led/led-sortiment-mit-180-leds-oem.html [Broken]. I have very little experience with wiring circuits (did AP physics a while back) and I'm not sure if this is even viable? I want to have around 10-20 LEDS consisting of 3 different colors powered by a battery(s). Can a simple button battery power a couple of LEDs for a reasonable amount of time? Should I buy a different voltage battery for each of the 3 colors? If this is even possible how should I go about this project? Thanks so much in advance for helping a noob out :)!
