Troubleshooting

These are some of the most common problems found when using Physical Bits. If your problem doesn't appear on the list please submit an issue. Thanks.

I can't connect to the Arduino!

There are multiple reasons why Physical Bits might fail to connect to your Arduino board. Here are some of the possible reasons:

Wrong firmware

The first thing you need to do is make sure that the firmware is correctly uploaded to your Arduino board. You can find the instructions here. After you uploaded the firmware please make sure you've selected the correct port and try connecting again.

Visual C++ 2010 Redistributable Package (Windows only)

If you're on Windows, you might need to install the Visual C++ 2010 Redistributable Package

Serial port permissions (Linux only)

On Linux, you might need to add your user to the dialout group (as explained here). The easiest way to do it is:

1. Open a terminal and execute sudo usermod -a -G dialout $USER
2. Log out and then log back for the group changes to take effect (some systems might require a reboot)
