And here we have our fully functional pocket weather station. It has an OLED display for you to enjoy the weather in a great manner. It also features a rechargeable battery with a USB charging port and honestly, the battery lasts quite a long time so you would barely want to charge it. Also, it has an Arduino Nano port for uploading or tweaking the code in the future.

The switch present on the outside is also very convenient to use. Besides this, the compact design of the device helps it fit even in the smallest of pockets!

Now, you can proudly carry the device wherever you go and flaunt your creation (or maybe actually use it as a weather station) 😜

If you are here, then I assume that you have built the project and it either worked which is great or it didn't which is also great because you not only will know how you build something but also how you do not build it and this kind of learning is very useful.

12.1 It Did Not Work 😲:

• 12.1.1 OLED Display Blank: You have either burnt out your OLED display or might be there is an error in your code (for example you might have forgotten to initialize the display). Recheck your code and try to check whether the display itself is working or not. If it is, then try tweaking the code.
• 12.1.2 All Readings are "NA": This will happen if your temperature sensor has an issue. It could be that you have done an error in connecting the temperature sensor to the Arduino board. Just recheck the connections. If the connections are right it is probably true that you have an issue with the sensor itself. Try replacing the sensor!
• 12.1.3 Works with a USB cable but not Battery: If this happens, then there is a problem with your battery or maybe the connections of the battery!

12.2 It Worked 🎉🎊: Great job mate. You overcome all the obstacles and finally are here, touching victory yourself and that is amazing.

Thank You :)
