About the project
Weather Lamp A IoT based 3D Printed Weather Simulating Lamp
Items used in this project
Weather Lamp is a RGB lamp made using Wiznet Pico WizFi360 and WS2812B LED's. The lamp simulates the real-time weather using the openweathermap.org API. It read parameters like cloud intensity, temperature, time and try to mimic the cloud colors, sun/moon and change the base color as temperature range.

Step 1: Designing & 3D Printing
Step 2: Circuit Connection
- Connect the WizFi 360 and WS2812B LEDs as shown in circuit diagram.
Step 3: Assembly
- Assemble all the parts together using quick glue.
Step 4: Getting Openweathermap API Key
- Go to openweathermap.org and create your account and verify it.
- Now login to your account and click on you profile or right-top corner and go to My API Keys.
- Copy the API Key that you see this will be used later in Step 6.
Step 5: Arduino Libraries Setup
- First go to Files->Preferences and copy paste the following URL in Additional Boards Manager URLs:
- Go to Tools->Boards->Boards Manager and search for Raspberry Pi Pico/RP2040 and dinstall it.
- Download the WizFi360_arduino_library-main.zip , Go to Sketch->Include Library->Add.Zip Library and select the downloaded Zip file.
- Now got to Sketch->Include Library->Manage Libraries and Search for ArduinoJson, Adafruit_NeoPixel and install them.
Step 6: Code Changes
- Download the Arduino Code and make the followig changes
- At Line.No 20 you have to edit your Wifi Name(SSID) and Password.
/* Wi-Fi info */
char ssid = "SSID"; // your network SSID (name)
char pass = "PASWORD"; // your network password
- At line 153 I have added 5 to hour and 30(Indian time zone IST 5:30) to Minutes and applied a maths to convert the APIs GMT time into ISt time zone.
- You may have to change the number(5 and 30) according to your tiem zone.
h = (h + 5) % 24;
minute = (m + 30) % 60;
- At line 282 you have to enter your locations Longitude, Latitude and You accounts openweathermap API key.
// send the HTTP PUT request
client1.println(F("GET /data/2.5/weather?lat=17.6795&lon=77.6051&appid=43f22249d3d42ec***********ca809b HTTP/1.1"));
Step 7: Code Compile and Uplaod
- Connect your device usinh MicroUSB cable.
- Select the board type and port from tools.
- Now click on uplaod code, it will automatically compile and uplaod the code.
- After code is succesfully uloaded the device will connect with provided wifi and show the output.
Note: I am using My PCs USB as the power source for the Weather Lamp, you can use a 5V adapter or a 3.7V Lithium Ion battery.
