F. Glow and Flow Copper Tape Circuits

Part 1: Paper Circuits – Light Up a Message! 💡💌

Your Goal: Create a card or paper craft with a working LED light. Make it Mean Something: Design it for someone special or to share a positive message. (Think: Electrical basics, Design, Interactive Art)

Materials:

• Cardstock/paper
• Copper tape
• LEDs
• 3V coin cell battery (e.g., CR2032)
• Clear tape, scissors, decorating supplies

Let’s Build:

1. Design: Who is it for? What will it look like? Where will the light go? Sketch your idea.
2. Plan Circuit:
   
   • Battery: + and – sides. LED: long leg (+) & short leg (-).
   • Draw two copper tape paths: One from battery (+) to LED (+), another from LED (-) to battery (-).
   • Optional Switch: How can you make a break in the circuit that you can close to turn it on? (e.g., a flap, or pressing the battery down).
3. Construct:
   
   • Stick copper tape firmly along your planned paths.
   • Attach LED: Bend legs flat. Place longer (+) leg on the positive path, shorter (-) leg on the negative path. Secure legs with more copper tape.
   • Add Battery: Ensure correct sides touch the copper tape paths. A small paper flap or tape can hold it.
4. Test & Fix: Light on? Great! No light?
   
   • Battery direction? LED legs correct? All tape connections tight?
5. Decorate & Share! Add your artistic touches.
