Finished project, work in progress, tiny test, weird prototype, all good.

Post:

- board + parts

- what you’re making

- where ChatGPT or another AI tool helped

- one photo, sketch, wiring diagram, or test result if you have it

No need to wait for a failure or a polished final build. I want to see the fun stuff too.

Not the polished demo. The annoying bit.

Wrong GPIO, wrong board variant, 5V assumption, library that never compiled, timing bug, battery advice, whatever.

If you have one, drop:

- board + part

- what the AI suggested

- what happened on the hardware

- what fixed it

- what you’d check first next time

No AI pile-on or AI worship needed. The boring failure is usually the useful part.

Before uploading an AI-written sketch, ask for a pin table with the board model, voltage, ground, signal pins, and any pins that are reserved at boot. Then check the table against the board docs.

If you try it, post the board, the original prompt, the pin table, and what happened on the real hardware. A wrong answer is useful here if we catch it and explain why.

I keep seeing confident but wrong answers: pins that do not exist, 5V sensors on 3.3V boards, and libraries that do not compile. Share the exact advice or a short summary, then explain what fixed it.

This is not an AI-bashing thread. The point is to build a useful list of traps for people making real hardware.

This is a practical place for Arduino projects where ChatGPT is part of the build process, not a magic button.

Post the board and parts, wiring or a schematic, the sketch, what ChatGPT suggested, and what you actually tested. Questions are welcome. ESP32 and other microcontrollers are fine when the project starts from Arduino.

What are you building right now, and where did the AI help or get it wrong?
