5€ WLan RGB-LED
you will need 4 additional Libraries in your Arduino-IDE:
- Adafruit NeoPixel
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 ;-)
