A kind of lightweight ESP32/ESP8266 webserver API and a NodeJS web UI to control an Infinity Cube built with 144 leds/m WS2812B Led Strip !

• 28 effects and 54 palettes
  • Some effects are calculated using 3D coords of the cube's edges (for maximum satisfaction)
• Customizable effect speed and intensity
• 3 customizable palettes
• Simple UI with color, effect and network settings
• Access Point and station mode - automatic failsafe AP see ApiServer
• Ability to disable leds on the strip to avoid overheating (in my case I disabled leds behind the corner covers)
• Possibility to rescale the brightness range
• Controllable using integrated Joystick
• Possibility to use an I2C 128x64 screen to monitor status (with configurable auto sleep)

• FastLED
• ArduinoJson
• WiFi
• ESPAsyncWebServer
• AsyncTCP (for ESP32) or ESPAsyncTCP (for ESP8266)

• Upload the InfinityCube code to your ESP, it will fail to connect to WiFi and setup an AP
• Connect to the AP with default credentials InfinityCube and 123456789
• Access the config page at http://{ESP_IP}/setup (usually 192.168.4.1, but the IP is printed over serial)
• Configure your Wifi settings
• That's it, you can now access your ESP over your network

The API is exposed over 2 endpoints

• http://{ESP_IP}/setup : for Wifi configuration
• http://{ESP_IP}/api : for light control
  • GET : http://{ESP_IP}/api?palettes=0 to get the list of palettes as JSON

  {
      "Primary Color": 0,
      "Dual Colors": 1,
      "Tri Colors": 2,
      "Vintage 57": 3,
           ...
  }

  • GET : http://{ESP_IP}/api?effects=0 to get the list of effects as JSON

  {
      "Solid": 0,
      "Rainbow": 1,
      "Strobe": 2,
      "Strobe Random": 3,
           ...
  }

  • GET : http://{ESP_IP}/api?status=0 to get the current state as JSON

  {
      "effect": 0,
      "palette": 0,
      "primary_color": 16711680,
      "secondary_color": 65280,
      "tertiary_color": 255,
      "speed": 128,
      "intensity": 128,
      "brightness": 0,
      "net_ssid": "SSID",
      "net_pass": "PASS",
      "net_ip": "192.168.0.1",
      "net_gateway": "192.168.0.254",
      "net_mask": "255.255.255.0"
  }

  • POST : http://{ESP_IP}/api a POST request to that endpoint with JSON Object containing one of the following field will modify it and return the new status (same as previous request)

  {
      "effect": 0,                /* The current effect, will roll over if overflow                                       */
      "palette": 0,               /* The current palette, will roll over if overflow                                      */
      "primary_color": 16711680,  /* The primary color as a 24bit RGB value as an unsigned int                            */
      "secondary_color": 65280,   /* The secondary color as a 24bit RGB value as an unsigned int                          */
      "tertiary_color": 255,      /* The tertiary color as a 24bit RGB value as an unsigned int                           */
      "speed": 128,               /* The effect speed as an unsigned 8 bit value, will therefore roll over if > 255       */
      "intensity": 128,           /* The effect intensity as an unsigned 8 bit value, will therefore roll over if > 255   */
      "brightness": 0             /* The master brightness as an unsigned 8 bit value, will therefore roll over if > 255  */
  }

• Deploy the NodeJS server
• Change the API IP in the top right corner (or for permanent change, edit it in Api.js)
• You can now control the leds

• FastLED
• ESPAsyncWebServer
• WLED

• Axios
• LiquidJS
• Bootstrap ColorPicker
