pinMode(led, OUTPUT);
}

void loop () {
digitalWrite (led, HIGH);
delay(500);
digitalWrite(led, LOW);

I tried that, nothing worked.
also in the Arduino IDE I can't select

I am guessing you are on Windows????

• When you plug in your ESP32 to your PC, do you hear a sound? If not, try a different USB cable.
• Does Windows say anything about installing drivers failed? You might need to manually install the drivers.
• If you open the device manager of windows are there any USB devices listed (after you plugged in the ESP32) that have no drivers installed? Then you most likely need to manually install FTDI (USBtoSerial) drivers.
• I needed to install separate drivers for the onboard USB of my ESP32. In my case it was for a CP2102 chip. You can find the drivers here: ESP32.net.
• Did you try to use a different USB cable?

And last, some ESP32 boards need to be set manually into bootloader mode. On my board that would be pressing the RESET button and keep it hold, then press the USR button and keep it hold, then release the RESET button, then release the USR button. Might be different for your board.

Thank you,,,
The problem was the driver CP210x is missing
and the cable wasn't good, even though I tried 4 or 5 different cables and finally I got one working.

Also, if you working on a laptop, make sure it is on full performance and plugged in.

Holding down the "Boot" button on my ESP-WROOM-32 while the Arduino IDE download the program worked. After the download I had to push the "EN" button to run the program. It did NOT start on it's own.

Hey, anyone here? I have a similar issue but unlike this one, I can select my COM Port and the drivers are also up to date. However, what I am finding out of place is that in the COM Port list I am getting some 17 options for COM1 even though nothing else is connected to the laptop. Any ideas?

you can get those COM port options in Device Manager
