How do I connect an Arduino to a USB port?

Connect your board to the computer by attaching the USB cable to the Due’s Programming port (this is the port closer to the DC power connector). In the “Tools” menu choose “Serial Port” and select the serial port of the Due. Under the “Tools > Boards” menu select “Arduino Due (Programming port)”

Why is my Arduino not connecting?

First make sure your board is on (the green LED is on) and connected to the computer. The Arduino Uno and Mega 2560 may have trouble connecting to a Mac through a USB hub. If nothing appears in your “Tools > Serial Port” menu, try plugging the board directly to your computer and restarting the Arduino IDE.

What kind of driver does the Arduino Uno use?

The Arduino Uno and Mega 2560 use standard drivers (USB CDC) provided by the operating system to communicate with the ATmega8U2 on the board. Other Arduino boards use FTDI drivers to communicate with the FTDI chip on the board (or in the USB-serial convertor).

What to do when you upload code to Arduino Uno?

If nothing appears in your “Tools > Serial Port” menu, try plugging the board directly to your computer and restarting the Arduino IDE. Disconnect digital pins 0 and 1 while uploading as they are shared with serial communication with the computer (they can connected and used after the code has been uploaded).
