*Make the connections as shown in circuit diagram.

*You can use WS2812B LED Strip instead of individual LEDs.

*The Data pin is connected to pin D4 of ESP8266,GND to GND and 5v to Vin of the NodeMCU.

*Make sure that you use 4 LEDs for each wall(4 LEDs x 4 walls = 16 LEDs),7 LEDs for cloud and 2 LEDs for Sun/Moon(3D printed Small Circe).

*The ESP8266 board is placed under the base , the base has a 3D printed cover to cover it.

*Open the code given in Arduino IDE.

*Code: https: https://drive.google.com/file/d/1MlS570K5l1ZHv9XbCG5qR2Kd_7NdueyC/view?usp=sharing

*Make sure that you have included every library's that are mentioned in the code.

*Now you have to edit this

String OPEN_WEATHER_MAP_APP_ID = "App_ID";
String OPEN_WEATHER_MAP_LOCATION_ID = "Location_ID";

*Open the browser and search for www.openweathermap.org.

*Create a account and login into that website.

*Click on API keys copy the key and paste in the program at APP_ID.

*In the same website search your location open the result and copy the last number from URL and paste it at LOCATION_ID.

*The MAP_ID and LOCATION_ID will be similar to mine.

*Enter your Wifi_name at ssid and your Wifi password.

const char* ssid = "Wifi_name";
const char* password = "password";

*Now change the Time zone as per your country Time Zone

int timezone = 5.5 * 3600;

As per India the Time Zone is 5:30 so I have typed 5.5 similarly you can type your Time Zone.

*Now connect the ESP8266 to your PC, select the port and upload the code.

I have used 5V micro USB Charger for powering this device.

Make Sure to 3D print cloud set the infill value to 0% in slicing software.
