Materials you will need
For making the board:
-1 piece of cardboard (I used the top of a paper box so my board would look more like a canvas)
-Black cotton material (20"x20")
-Several different colors of felt ( I used blue and purple) for stars
-Piece of white felt (for moon)
-Needle and thread
-Copper wire (or any conductive wire) 12"
For the electronic part:
• LilyPad Arduino board
• LilyPad LEDs (6 white)
• Li-Po battery
• Conductive thread
• LilyPad tone for sound
• LilyPad FTDI basic
• Mini-USB cable
• FTDI driver
Step 1: Making a Plan
I then mapped out how I would sew to connect the LEDs to the board and complete the circuits. This prevents getting circuits crossed or having to sew inefficiently to complete the connection. To ensure that my negative lines didn't intersect with my positives (which would prevent the circuit from working) I used the back of the board for the negative lines and the front for the positives. The circuitry sketches I used are attached.
All of my negative lines (from the LEDs and the tone button) went back to the same petal on the board-- which I label as "Ground" on the sketch.
