I am new to arduino, and I just can't figure out what is wrong with uploading my code. I have selected the correct port and board, but the problem still seems to be there. I feel like I have tried everything to upload my code, which is why I am here to ask for help.
No device found on COM3
An error occurred while uploading the sketch
If you do “tools>port” . Is your device there ? It may not be on com port 3 but on a different port .
If it is shown as present , then it might be a driver issue . You need to add a specific driver for this new board.

Worth a good read as this chip is somewhat different ( esp
Operating voltage) from the chip on the normal beginners choice of a UNO...
I experienced this problem while the Due was running a sketch that utilised the Native USB (SerialUSB object).
The solution was to disconnect the Native USB during update.
The initialisation code
SerialUSB.begin(2000000); // Initialize Native USB port
while (!SerialUSB); // Wait until connection is established
then ensures the sketch stalls until the USB is connected.
