Hi I have my App that sends ON1 and OFF1 to control led so the code is so simple I just need to change some commands to make it respond to what I send from my phone and I am new to ESP8266 01with 8 pins .
I need a clean and simple code Thank you! :slight_smile:
Anyone familiar with codes can easily modify it...!

This translates to "Need idiot to writce code for me for free"

Hi 74Younus,

Please paste your last attempt and please clarify the snippets you're struggling with most.

Thank you.
