Please provide a detailed description of what you mean by "cannot connect to the computer".

#3

but cannot connect to the computer

Please provide more information, are you not able to see the ports under IDE-> Tools> Ports?

  • Describe the behavior of L Led on pressing Reset Button. (It must Blink twice very fast).
  • Go to: Arduino IDE > File > Preferences > Show verbose output: Select both options: “Compilation” and “Upload”. Then try to upload the Blink example (Arduino IDE > Files > Examples > Basics > Blink) and please send to us the copy of the whole text shown in the console.
  • Connect the board to a different computer and check if it has the same behavior.
