ESP32 FastLED Web Server

Work in progress ESP32 port of https://github.com/jasoncoon/esp8266-fastled-webserver

Update 09/08/2020: rorosaurus updated to use ESPAsyncWebServer as async server library. Also fixed AP mode to work standalone, with no internet connection needed. Large js files are gzipped, and the FatFS filesystem is used (instead of SPIFFS) to minimize chance of starving the watchdog timer while serving so many large files. I'm using this tool to upload FatFS from Arduino IDE.

Control addressable LEDs with an ESP32 via a web browser over Wi-Fi.

Features

Currently Working:

• DemoReel100 patterns
• Static web app file serving from SPIFFS
• Ability to adjust these settings via the HTTP REST API:
  • power on/off
  • brightness
  • pattern
  • autoplay on/off
  • autoplay duration
  • speed
  • palette
  • auto palette cycling
  • palette duration
  • solid color
  • twinkle speed/density
  • fire cooling/sparking
• Setting storage in EEPROM

Currently Lacking:

• WebSockets for automatically refreshing/syncing web clients

Requirements

Hardware

ESP32 Development Board

Adafruit HUZZAH32 – ESP32 Feather Board

or

WEMOS LOLIN D32

or

An ESP32 development board of your choice

Addressable LED strip

Adafruit NeoPixel Ring

Other hardware:

• 3.3V to 5V Logic Level Shifter (required if LEDs "glitch")
• Octo Level Shifter FeatherWing (tidy level shifter PCB)

Recommended by Adafruit NeoPixel "Best Practices" to help protect LEDs from current onrush:

• 1000µF Capacitor
• 300 to 500 Ohm resistor

Software

• Arduino
• ESP32 Arduino Libraries & Tools
• Arduino ESP32 filesystem uploader
