Elena Blogs for a Change

I recently finished the holiday LED project where we created holiday cards containing small LED lights connected to circuits made of copper tape. First, you created image or pattern design using paper scraps on the front of your card. Then, you make a plan for the circuits. Your circuit design must be thoroughly thought through in order for the lights to work. The type of circuit you must build is called a ladder, because the LED wires look  like steps of a ladder, placed on the two main beams on either side of the circuit (made of copper tape). See how the circuit looks like a ladder After that you solder metal onto the breaks in the copper and use the melted metal to stick the LED wires onto the copper tape as well. And then, after adding a coin battery and ending the circuits, your card should be all set. I think I learned a lot about circuits and engineering in this project. If I could change anything about it though, I think I would have a more organized way of buildi...
