Project Design/Guidance Temperature monitor

Title: I built a DIY PC temperature monitor using Arduino! 🌡️💻

Post:

Hey everyone!

I built my own DIY PC temperature monitor using an Arduino Uno R4 WiFi, an LCD screen, and a temperature sensor.

The idea was to monitor the temperature inside my PC case and display it on the LCD in real time. I also added a buzzer that activates when the temperature gets too high.

It's a simple project, but it was a fun way to learn more about electronics, Arduino, and PC hardware!

What do you think? Do you have any suggestions for improving this project? 😁

"Reactor core stable" or "meltdown risk: normal" is more interesting to someone passing by then "temp OK". Have some fun with the messages. Flashing " THERMAL RUNAWAY EMIMENT! TAKE COVER NOW" followed by "just kidding" randomly can be fun too

Also, I didn't change the case because I like vintage cases.
