In this tutorial we will show you how to make a Halloween card with glowing LEDs! To do this we will use some Bare Paint, a battery, and some surface mount LEDs.To find out more about Bare Paint visit our website at www.bareconductive.com!
Look carefully at the bottom of your LED and make sure you've identified the positive (+) and negative (-) sides. If you're not sure which is which, test it by touching the ends to the battery's positive (+) and negative (-) pins. Make sure you place the LEDs in the right direction. Otherwise they won't light up!
Glue the LED to the paper using Bare Paint.
Make sure the paint doesn't connect between the positive (+) and negative (-) legs!
Look carefully at your 3V coin cell battery, and identify which side is positive (+) and which is negative (-). The positive (+) side may have a green line indicating its polarity.
Bend the legs of the battery so that they're facing upwards, and stick them through the back of the paper so that they make contact with the paint on the other side. If the paint is not totally dry and you're worried about making a mess, you can let the paint dry first; otherwise make sure you're careful while handling the paper!
The back should look like the third image shown here.
