A STEM Project: An Interactive Embroidered/Foil Quilled Dandelion Which Activates LED Lights When A Sound is Heard Using A Hyperduino To Simulate Seed Pods Blowing in the Wind

Video of the Interactive Embroidered/Foil Quilled Dandelion Which Activates LED Lights When A Sound is Heard Using A Hyperduino To Simulate Seed Pods Blowing in the Wind

I was inspired to create this interactive design of a Dandelion with seed pods blowing in the wind, after viewing this dandelion painting by Jie Qi. https://technolojie.com/pu-gong-ying-tu-dandelion-painting/  I use a Hyperduino, LED lights and a microphone to activate the lights in sequence to simulate the seed pods blowing away from the dandelion. The microphone is activated when a sound is heard. This design is a small basic design that can be expanded upon if you would like to create a larger design similar to Jie Qi's painting.

Disclaimer: 

- Adult supervision is recommended when using the Hyperduino.

- Do not operate unattended.

 I used 65 lb cardstock to make the presentation boxes which houses the Hyperduino with LED lights and a microphone. I used Aleene's tacky glue in a glue bottle and Glue Dots to make the presentation boxes. An adhesive foam sheet is needed to mount the Hyperduino in the presentation box. The dandelion image was created in Turtlestitch and embroidered on a Brother PE 800 embroidery machine. Here is the Turtlestitch code which creates the design. https://www.turtlestitch.org/users/Elaine/projects/Dandelions%20For%20Light%20Box 
A Silhouette version was created by exporting an SVG from the Turtlestitch program and opening it with the Silhouette software.  The image was then Foil Quilled on vellum paper. 

Here is the PDF.

Here is the .Studio file.

Here is the SVG.


Make the Light Box

Align all of the box edge pieces so that they are oriented in the same direction. 
  
Mountain fold all of the horizontal edges so that the pieces look as above.

Apply glue to the horizontal tab.  This tab is the shorter of the two horizontal edge tabs.

Adhere the glue by pressing down on the paper and exposing the bottom edge.  The piece will become flat.

Once the glue has dried, reorient the edges to make a rectangular box. Repeat the above three instructions for the other three box edge pieces.

The two tabbed sides are different.  On the side with all the edges aligning,  fold the two small tabs inward as shown above.

Apply glue to the two small tabs.

Adhere the one tab on the left side and then apply glue to the top of this tab.

Adhere the other side tab to complete the right side.

On the left side of this piece where the side edges are misaligned,  fold the two small tabs inward and then apply glue to the them.

Fold down the top tab and adhere. 
 
One side of the light box is completed. Repeat so that all of the sides look as the photo above.

In the photo above, I rotated the piece by 180 degrees from the previous photo. On one side of the first piece, apply glue in the three corner areas as shown above. Each surface will adhere to different parts of the adjoining piece.

Adhere the corner of another side piece to the two glued areas and then fold up the tab to complete the corner.

Repeat for the other three sides.  Apply glue to the top surface of all four sides of the square.

Insert the LED Light pattern and adhere this piece to the glue. 

Apply glue to the inside edge of the four edge tabs.  Fold the tabs down and adhere to the box.

LED light panel completed.

Cut the vellum or embroidery to a 6 x 6 inch size and sandwich two borders on either side of the design with glue.

Make the Hyperduino Presentation Box
 
Create a three sided box by folding the dotted areas as shown above

Apply glue and adhere the tab as shown above to create a triangular prism.  These triangular prisms create a sturdy support structure for the box.

Apply and adhere the bottom tab. This side will now be at a right angle to the bottom. Repeat this instruction and the one above for the other side of the box.

Side view of three sided box. Set this aside to make the square sides.

Fold the dotted areas and apply glue as shown above.  Notice there is no glue on each side (triangular area) of the tab.  This area needs to be be free of glue as this will be where the sides slide into one another. Adhere to create another triangular prism.

Apply glue to the three outer flat edges and the bottom tab as shown above.

Align the bottom flat edge of the square side to the three sided box and then slide the two side tabs of the three sided box into the square piece. Align the top edge to create a mitered corner. Adhere the bottom tab to create a triangular prism.

Completed side. Repeat for the other square side piece.

Completed presentation box.

Cut four 2 x 2 inch  foam squares. (I mentioned three in the files...I needed another foam square...this depends on the thickness of the foam.)

Glue the foam squares on top of one another.  I used Glue Dots.

Adhere the foam squares in the middle of the presentation box with a Glue Dot.

LED Lights and Microphone

Attach the Microphone as shown above with the black wire going from  the microphone G to ground on the Hyperduino, the white wire is going from the microphone A0 to A0 on the Hyperduino and the red wire is going from + on the microphone to 5V on the Hyperduino.

Place two Glue Dots on the bottom of the Hyperduino and insert the Hyperduino into the box.  Place the Hyperduino on top of the foam stack.

Stretch a Glue Dot and adhere it to the base of each LED light.

Insert the LED lights into the holes in the LED insert.  The placement of the lights will effect the sequence of the lights.  I have coded LED light number 13 to go on first, light number 12 and so on, decreasing to light number 8.

Tape the LED Insert onto the presentation box. The LED light box is ready for the embroidery or the Foil Quilled design to be attached.

The embroidery/Foil Quilled dandelion is attached with a pretty paper cover which is slide over the edge of the LED Light box. Fold the two tabs upward on the pretty paper pieces.

Glue the four corner tabs to create a cover for the box.

Lay the frame over the top of the LED insert. This photo shows the Foil Quilled version of the dandelion.

The microphone is not attached to the presentation box as the microphone needs to be adjusted for sensitivity. The sensitivity threshold is adjusted via a screw on the potentiometer. The sensitivity increases as you turn the screw clockwise and decreases as you turn it counterclockwise. Plug the Hyperduino into your computer and the microphone light should be illuminated. At this point you can adjust the microphone's sensitivity. I had to turn the screw numerous times to get the right adjustment.  I am using 525 as my analog reading for sensitivity.

Here is the code I used in Snap For Arduino with the sensitivity of 525 for the microphone.  You may need to change the value for your microphone.

This photo shows the embroidered version of the dandelion with an LED light illuminated behind the frame.
