Candy Corn Light
This Halloween it is time to make your own interactive candy corn light!
What You'll Need:
Teknikio Diamond RGB LEDboards,
Colorful felt pieces
Scissors, sewing needle, non-conductive thread
Plan your Circuit
This circuit contains an LEDboard, a battery and conductive tape. When conductive tape is connected to one of the LEDboard pads, it will light up. We will be using conductive thread to secure our conductive tape to the felt and to sew our circuit connections.
Cut out Candy Corn shapes
Cut out candy corn template. On the candy corn template the pieces are labeled with a color either orange, white or yellow. Trace the templates on to felt using a marker or chalk. Cut out the template shapes from the correct color of felt. You should have six pieces, as shown on the illustration.
Sew felt pieces together
Overlap your orange piece of felt so that it is over the yellow and white pieces of felt. Using non-conductive thread sew the orange felt to the yellow felt with a running stitch, make a knot and cut the excess to complete the stitch. Then repeat for the orange and white piece of felt. Make sure that all three colors are visible.
Attach circuit pieces
Take one of the completed candy corn felt pieces. Change your thread to conductive thread. Attach the battery board to the orange felt by holding it in place on the fabric and looping around the pad marked with “+” 3 - 5 times.
Connect the circuit
Place three strips of conductive tape on the opposite side of the felt from the batteryboard. Use a running stitch and conductive thread to connect the tapes to the positive side of the batteryboard. This will be your side B.
Tip: You can lift the batteryboard out of the way to sew the conductive tapes on since it is only sewed to one side.
Connect the circuit
Put side B off to the side and grab the other blank candy corn felt piece. This will be called side A. On side A you will sew the diamond LED on using separate conductive threads. Start by placing three strips of conductive tape on the inside of Side A. On the outside of side A, place the diamond LED. Connect the “R” side of the LED to the middle conductive thread. To do this, hold the diamond LED and then loop around the “R” hole and the middle conductive tape 3-5 times. Use a running stitch to finish securing the middle conductive tape. Tie a knot and cut the excess thread off. Then repeat these steps for the “B” and “G” parts of the LEDboard.
Tip: Since the bottom of the diamond LED is not attached you can lift it up when sewing your conductive tapes on. Make sure that “R,” “G” and “B”are not connected together and they all are connected to their individual conductive tape.
Connect the circuit
You have connected the positive side of the circuit, now we need to connect the negative side of the circuit. Lay down Side A and Side B next to each other. Use conductive thread and connect negative pad of the LEDboard to the negative side of the batteryboard. Make sure that the candy corn pieces can still fold together after you sewed the conductive thread on.
Prepare the stuffing
Next, we will prepare the stuffing for our project. Since our tapes are inside of our candy corn, we will need to cut three holes into the stuffing. Make sure that the holes align with the conductive tapes.
Test your Circuit and Decorate
At this point you can insert your battery into the batteryboard. Make sure the “+” faces up to match the “+” on the batteryboard. Press two of the conductive tapes together. Your LED should now light up!
If your LED flickers or does not light up:
Check that your battery has enough power to charge the LED! If you have a voltmeter make sure the battery is above 2.5 volts.Check that your positive and negative connections do not cross or touch.Check that your thread is tight around all the conductive holes.Check that your stuffing holes line up to the conductive tapes.
You may need to take out and re-sew your connections.
