Hello friends,
I’m a beginner and I’m seeking help after exhaustively trying to fix bugs and make my way forward to work with ESP32 board.
While I make my garden irrigation automation project. I am also ensuring, that this project becomes a bootstrap project for anyone wishing to start off with ESP32.
Let’s come directly to the BUG and COMPILATION ERROR.
