In this video I show the details of how my pattern programmer for the NeoPixels work.
This little project is a continuation of the leds I used on the chaotic pendulum.
With the software you can draw patterns by hand or load up an image. The software programs the values to the arduino’s EEPROM, this means the device can be disconnected and powered down, while still preserving the pattern. After programming no PC is required anymore.
I used this little installation with great success as a quick way to add interesting RGB light effect to clothing on Makerfaires.
