I came up with the idea to make a weather station based on an ESP32. It will connect to the internet and have three LEDs: green when it’s working, red when there’s an error or no internet connection, and blue when it’s connected to the internet. I’m building it on a breadboard because soldering would be overkill lol. The data will be fetched from a free API on the internet. The ESP32 will connect to my home Wi-Fi. And i will see data on my oled screen

I came up with the idea to add a button and a DHT sensor to it. I added them, and this is what the final prototype looked like. Everyting worked perfectly

1/1/2026 2:40 PM - Stupid Idea

I decided that maybe I would solder it onto a PCB. That was a tragic idea. I forgot the pinout on my USB, and the solder joints came out really weird. I couldn’t disconnect them, and luckily only the ESP32 was damaged.

Demo Video Here ;)

I fixed everything and left the project finished. That’s the end. It’s a very cool and interesting little project—I really like it. There was a lot of programming involved, and it taught me a lot. I think it’s a pretty cool and fairly advanced project, even though it’s on a breadboard, and I don’t want to change that because it would just be overkill. Thank you. Additionaly i added some fresh code

I made schematic for this project. made it on paper because why not :) last step is to make the 3D view of case. i want to add that i wont add any case because i dont want and its just a prototype

1/27/2026 8:52 AM - CAD CASE INFORMATION

n terms of the case/CAD design, I do not want to add this; I want to leave the project completed as it is. I previously mentioned that it would be without a case, so this is the end of the project. .;)
