Fritzing

controll RGB-LEDs via Smartphone or Tablet

you will need 4 additional Libraries in your Arduino-IDE:

- ESP8266

- Adafruit NeoPixel

- WiFiManager

- RemoteXY

Links to these libaries are provided in the 'External-Links' section.

After uploading the sketch, you can conntect to the ESP8266 Accesspoint, you will then be asked to configure your network-settings - once this is done, the ESP8266 will close the Accesspoint and connect to your WLan - now you can open the RemoteXY-App and play with the colors ;-)
