This great project was sent in to us by Vaishnavi. She writes:
I built this skirt over the summer to learn about
electronics, programming in Arduino, and using microcontrollers. The skirt
has 96 individually addressable LEDs, four of which are NeoPixels, soldered
with 26 gauge wires in parallel to the Adafruit Gemma. It is programmed in
Arduino using the NeoPixel library to cycle through all the colors, (0,0,0)
to (255,255,255), in a ripple effect. My plan is to take it further by
adding a sensor so that the lights change based on a variable, such as the
rate at which I spin. Some of the issues I encountered was preventing the
LEDs from shorting because as the skirt moved, the wires had a chance of
touching. The solder points on the LEDs were also very small and close
together so it was tough to solder all the wires without making them touch.
An interesting issue I faced was troubleshooting irregular behavior of
random LEDs, which I later found out was caused by loose and shorted wires.
A solution that seemed to fix the shorting issues was varnishing over the
solder points so that even if two LEDs touched while I moved, it would not
short.Check it out on Instagram
