Esp8266 nodemcu onboard led help me

Projects Programming

Hello; I'm working on the nodemcu module. When I load the existing codes, the built-in LED on the module does not light. It only lights up during installation. For this, I want to combine both my codes and the built-in led lighting codes in the examples section, but I keep getting an error. Could you please combine these two codes and help me? Thanks.

Your topic has been moved from the Nano ESP32 category of the forum as it relates to a completely different board and processor

You forgot to include what this error is so only you know... It is always important to post the complete error message (if that is the error you are getting) How to get the best out of this forum - Using Arduino / Installation & Troubleshooting - Arduino Forum

What a big messy effort to make the onboard-led blink.

This does not need a library. Just a few lines of code

personal information is not correct so it's okay. Thank you for the code. I'll let you know after testing. @StefanL38
