I have recently brought an ESP 32 WROOM, and ive been watching a video by Drone workshop, i copied his blink sketch from the article Getting Started with the ESP32 - Using the Arduino IDE when i try to upload it the IDE tells me ledPin was not declared in this scope, however I have been staring at …

Look at the top of the code, things like esp32-blink are highlighted, so the IDE thinks its code.

If your screenshot is the whole code, there is something missing. The starting comment does not have a start, only the end. I doubt that the compiler is happy with that.

I'm not 100% sure as i'm not an expert in coding but apart from the comment, can you maybe use #define ledPin 2 or does that not make a difference?

[image] ep01256: can you maybe use #define ledPin 2 or does that not make a difference? The problem is almost certainly that the code does not start with a /*, but since the OP only posted a picture of part of the code, it's hard to tell. It is likely that #define wouldn't have worked either…

Hi, Think we need to know what is going on here first. Looks like a copy and paste code. [code] Tom.... :grinning_face_with_smiling_eyes: :+1: :australia:

ledPin was not declared in this scope, unsure why?

Hi,
I have recommended to the moderators to move your thread to a more appropriate section.

Can you please post your code, rather than screen captures
