Chainable, surface mounted RGB LEDs work in paper circuits!
After spending a couple of days prototyping, I've completed my first paper circuit using individually addressable neopixels, otherwise known as surface mounted RGB LEDs! Soldering them was trickier than I'd anticipated, however! I'd originally planned to use three lights in this model, but a soldering mishap resulted in my using only two. I love the way that the lights change colors at the press of a button! (See video below).
