ESP2812b

ESP2812b is a simple API for controlling NeoPixels and other WS2812b/WS2811 addressable LED strips with short JSON files.

Libraries Used

• ArduinoJson
• Adafruit's NeoPixel Library
• ESP8266 Arduino Core

Endpoints

• /solid

  • Sets all LEDs to the same color
  • /solid?c=FF0000

• /pattern

  • Sets LEDs to repeating set of array of colors
  • /pattern?json=["FF0000", "009900"]

• /chaser

  • Similar behavior to /pattern with the addition of a light chaser effect
  • /chaser?json={"p": ["FF0000", "00FF00", "0000FF"], "time": 300}

• /sparkle (Not Implemented)

  • Displays a pattern onto the strip with random flashes of a specified color
  • /sparkle?json={"p": ["FF0000", "009900"], "time": 100, "spark_color": "FFFFFF"}

• /json

  • Test area to ensure json parsing is working as intended
  • /json?json={"any": "valid json works", "here": [6,42]}

All colors are hex RGB values, all times are in milliseconds
