4.  Design the Card and Build the card:

                          Design the card.
                          ◦    Draw or print the greeting card design on cardstock.

                          ◦    Plan where the LED will be placed (e.g., as part of a candle or star in the design).

                          Attach the LED poke small holes the card to insert the LED leads.
                          ◦    Bend the LED leads flat against the back of the card.

                          Prude the Circuit

                          ◦    Use copper tape to connect the longer lead (anode) of the LED to the positive side of
                              the battery.
                          ◦    Use copper tape to connect the shorter lead (cathode) of the LED to the negative side

                              of the battery.
                          Add the Battery:

                          ◦    Attach the battery to the back of the card using a battery holder or tape.

                          ◦    Ensure the positive terminal of the battery touches the copper tape leading to the
                              LED’s anode and the negative terminal touches the cathode.

                  5.  Integrate a Switch (Optional):
                          Create a switch using a foldable paper tab that closes the circuit when pressed.

                          Place the switch in the copper tape path, ensuring the circuit is only completed when the
                          tab is pressed.

                  6.  Test and Finalize:
                          Press the switch (or close the flap) to light up the circuit.

                          ◦    Troubleshoot any loose connections.

                          Final Touches:
                          ◦    Secure all components with tape or glue.

                          ◦    Decorate the card with drawing , sticks or design.
