Step 1: Supplies
Step 2: Meet Sparkle!
Connect to a 3V power source and the surface mount LED on the Sparkle board will blink and bling.
Connect LEDs to the Sparkle board and they too will blink and bling.
It has three different blink patterns programed into the board. Depending upon how you sew the LED sequins to the board you will have a different blink pattern.
For detailed information on Sparkle connections please see Aniomagic.
Step 3: Design your circuit
I have uploaded a hi-res image of my schematic to my flickr account for you to study.
Please note: The positive and negative traces should never ever ever touch.
Step 4: Sew the positive and negative traces
One positive trace.
One negative trace.
Sew parallel lines close enough to connect your LED sequins but, do not let the two traces touch or overlap.
Using a multimeter test for short circuits and resistance.
Once you are confident that the traces are sewn in the correct locations and have passed the multimeter test use the satin stitch sew over the conductive thread again. This is not necessary however it serves as a decorative element as well as protecting the conductive thread from the elements and possible sort circuits.
