Hey guys! I Hope you already enjoyed my previous project "Arduino Robot 4WR" and you are ready for a new one, as usual I made this tutorial to guide you step by step while you make your own electronic project.
During the making of this project, we tried to make sure that this instructable will be the best guide to assist you while you chose to make your own electronic based project, so we hope that this instructable contains the needed documents.
This project is so handy to make specially after getting the customized PCB that we’ve ordered from JLCPCB to improve the appearance of our electronic device and also there is enough documents and codes in this guide to allow you create your beautiful weather station.
We've made this project in just 2 days only, just one days to get all the needed parts and finish the hardware making and the assemble, then one day to prepare the code to suit our project and hen we have started the testing and the adjustments.
What you will learn from this instructable:
- Making the right hardware selection for your project depending on its functionalities.
- Understand the weather station workflow.
- Prepare the circuit diagram to connect all the choosen components.
- Produce your own PCB design.
- Solder the electronic parts to the PCB.
- Assemble all the project parts.
- Start the first test and validate the project.
Step 1: How the Weather Station Works!
As always I start my project with this short description, our project is based on a NodeMCU dev board which already includes a WiFi modul to connect to the internet in order to receive the weather forecast updates and display it on the OLED screen, which is connected to the NodeMCU through the I²C communication port.
In order to make all this happening without problems, some libraries should be included in source code. These libraries are available in open source and you can add them directly from your Arduino IDE
The weather station will also get the Time and Date data from the internet and to do such feature we need to provide the NodeMCU the websites from where it will upload the Weather forcasts and the time date data. All of this will be explained in the Software section of this presentation.
Step 2: Circuit Diagram
This project is so basic one, no complexity in it, I used easyEDA online platform to prepare this circuit diagram that has all the necessary components for this project and some additional parts like a buzzer for some alarms and some LED outputs you can have the PDF format of the schematic or the PNG format from the download section below.
Step 3: PCB Making
After preparing the circuit ,I transformed this circuit diagram into a customized PCB design with a cloud shape to suit our project theme, all what we need now is producing this circuit design so I moved to JLCPCB the best and cheapest PCB producers to get the best PCB manufacturing service, JLC is a professional PCB manufacturer featured of large scale, well equipment, strict management and superior quality. as always all what you need is simply some clicks to upload the GERBER files of the PCB design and set some manufacturing parameters, than I wait just for three days to receive my order.
As you see through the photos, the PCBs are very well produced and this cloud shape will add a better appearance to our project

You can also download the Gerberfile for this circuit.
Step 4: Enclosure Design
I used than Solidworks software to design this enclosure where we will place the electronic components, and then I produced the designed parts through a CNC laser cutting machine.
you can download the DXF files for the enclosure parts
Step 5: Ingredients
Let’s review now the full components list of this project so we will need :
