Overview

This mini card will get you started with a simple paper circuit! You’ll need the template, one LED light, some copper tape, a battery, a binder clip, and some drawing or painting materials.

We will use the copper tape to connect a battery to the LED circuit sticker in a loop. The “+ side” of the LED circuit sticker needs to connect to the “+” side of the battery and the “-” point of the sticker needs to connect to the “-” side of the battery. This continuous loop will form a complete circuit, lighting up your LED!

Materials

  • 1 LED Circuit Sticker
  • 3V coin cell battery (CR2032)
  • Small binder clip
  • 7.25″ (18 cm) of copper tape or other conductive material, cut into 2 strips
  • One card from the circuit card printable. You can print it double sided or print just the first side.

Directions

1. Peel back some of the paper backing from one of the pieces of copper tape to get it started.

2. Run copper tape over both of the gray lines.

3. Make sure to leave a gap between the two strips of copper tape. Place your LED sticker over the outline and press it down for a count of 5. To achieve the best connection, avoid touching the adhesive with your fingers as much as possible.

4. Almost there! Place your battery + side up on top of the – circle. This way, when you fold the flap over, the positive side of the battery will make contact with the copper tape connected to the positive side of your LED. Fold the flap over along the dotted lines, then hold it in place with a binder clip.

5. Is your LED turning on? Excellent! If not, try these troubleshooting steps:

• Make sure your battery is + side up before you fold the page over.
• Press down on your LED for a count of 5 seconds to ensure a good connection.
• Check that the metal parts of the sticker are sitting on top of your copper tape, positive to positive (wide side of triangle) and negative to negative (pointed side of triangle).
• If that doesn’t work for you, check out our detailed troubleshooting guide.

5. Fold the card so that the circuit ends up on the inside. Now you can decorate and use your LED to tell a story or illuminate your artwork!
