A USB cable for Arduino is a cable used to connect an Arduino board to a computer or other device that has a USB port. The cable typically has a Type-A USB connector on one end and a Type-B USB connector on the other end.

The Type-B USB connector is the one that plugs into the Arduino board, while the Type-A USB connector plugs into the USB port on the computer or other device. The cable is typically about 20cm in length, which is a convenient length for connecting the Arduino to a computer or other device that is in close proximity.

The USB cable is used to transfer data between the Arduino board and the computer, allowing the user to program the board and upload sketches, as well as to receive data from sensors or other inputs connected to the board. It also provides power to the board, allowing it to be powered from the USB port rather than an external power source.

When selecting a USB cable for Arduino, it's important to choose one that is compatible with the Arduino board being used and is of good quality to ensure reliable data transfer and power supply.

Use this cable to connect your Arduino with a PC or any other USB compatible device. This cable is also needed to program your Arduino from a PC.
