Paper Circuits
Materials Needed:
Paper
Conductive Adhesive Copper Tape (Amazon or Adafruit)
Clear Tape (to tape down battery)
3V coin cell battery (Amazon)
LEDs (Amazon)
scissors (to cut tape)
Design your card.
Draw out the circuit. NOTE: Do not let the negative and positive tapes cross. Make sure positive (long) side of the LED goes to positive (+) side of the battery and negative (short) side of the LED connects to the negative (-) side of the battery.
Fold the corner of your page to create a switch for your battery.
Trace copper tape along circuit, folding back and forth to create corners.
Tape down one half of the battery with nonconductive clear tape.
Fold over your switch to connect the circuit.
Your card should light up!

You may have to tape down your LED. Alternatively, you may have built a parallel circuit. If so, follow this tutorial. (https://makezine.com/projects/paper-circuit-parallel/)
