After countless days and hours, I finally can upload my sketch into my NodeMCU successfully. But, just after that, I've got another problem.
If you've checked my previous post, you'll see I have two sketches. The first one is at my question and the second one is at my answer. After uploading the second one, I decided to upload another sketch, which is the first sketch. But when I check the result after the IDE says: "Done uploading", I know that the NodeMCU is running the previous program (which is written in my second sketch) based on what the Serial Monitor has printed. What I want is the result of my first sketch, not this. Anyone can help?

1Did you press the `reset` after uploading? – hcheung Jun 27 '22 at 00:40
