This instructable was created as part of the Instructables Build Night with Chibitronics at MakeICT.
We received Chibitronics peel-and-stick electronics for crafting circuits for an Instructable Build Night. These circuit stickers allow anyone to add effects to just about any item you can think of using lights (LEDs). Included were effect and sensor stickers so the lights could do more than just being on, they could be animated.
It was almost Christmas time, and everyone was taken care of. The next holiday to give cards was in February, so I decided I would make something personal for my special person. I like the idea of the Heartbeat effects sticker, what better effect could be added to a Valentine Day card?
