After you have uploaded the code to your Esp-01S, you need to pull the
ESP-01S programmer out of your PC and set the small switch on the side
of PROG to UART so that you can see the serial output of the ESP-01S in
your IDE. Once you have flipped the switch, you can put the programmer
of your ESP-01S back into your PC and view the serial output of your ESP-
01S to see if the connection to your WiFi was successful.
