Hi, I am new to Arduino. When I upload the code to the Arduino, it uploads but does not show output on the serial monitor. It keeps saying this ** "Port monitor error: command 'open' failed: Invalid serial port. Could not connect to COM11 serial port." ** When I upload the code. please see the screenshots below.
I am using an ASUS Vivobook 14 K413. Please help.
Have you installed the driver for the ch340?
I am not sure but on Device manager > ports I have USB-SERIAL CH340 (COM11)
