ESP32 FastLED Web Server

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

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

Features

Currently Working:

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

Libraries

• FastLED
• ESP32 Arduino Libraries & Tools
• ESP8266/ESP32 WebServer
