esp8266-ws2811-rgb-led-strip
NodeMCU based code for a HTTP based control for WS2811 LEDs
Features:
- Supports multiple WIFI setups; automatically hops between WiFis until the first working one is found
- Simple control of the WS2811 RGB LED strip using a HTTP server and query-parameter based requests
- Supports arbitrary length hex patterns:
- Can set all LEDs to the same color
- Can e.g. alternate two colors
- Can send one color per LED
Requirements
An ESP8266 module running NodeMCU, a blank filesystem, and one free pin
Installation
- Make sure your ESP8266 module is running NodeMCU. Flash if not.
- Connect the WS2811 to pin GPIO2 (or change the mapping in rgb.lua)
- Set up rgb.lua for the number of LEDs you have
- Put all
*.luafiles on the ESP8266 by e.g. using ESPlorer. - Restart your ESP8266
Usage
Webserver is running on port 80 after the module has started up. When a WiFi network is initially found, a "red-green-blue" test pattern is shown across the LED strip. If the strip remains dark, the module is not yet connected to your wifi.
