This app allows you to control a WS2812B Neopixel LED strip from your Android device over your WiFi network. You need to have a Spark Core or Particle Photon device properly connected to a Neopixel strip and the SparkPixels firmware loaded on the device. Get the firmware and see schematic and additional documentation at https://github.com/sparcules/Spark_Pixels.

Spark Pixels is a mode selector remote for your Neopixels. Select a mode, adjust brightness, adjust speed.
Spark Pixels is NOT a mode/LED sequencer creator. All modes are coded in the Particle sketch.
