The following instructions walk through setup needed to complete this tutorial.

For this tutorial, participants will want to install Mu editor.

Windows users may install Mu from here.

Mac users may install Mu from here.

Linux users must be running Python 3.6 or newer. Install by running sudo apt install python3. Then, install pip3 by running sudo apt install python3-pip.

Next, create a virtual environment: python3.6 -m venv pyohiocp. Follow the instructions to install venv if it is not already installed. To activate the virtual environment, run source ~/pyohiocp/bin/activate. Once inside the virtual environment (pyohiocp), install Mu by running pip3 install mu-editor.

Linux users must add their user to the dialout group to access the serial console output. From the command line, run nano /etc/group. Find the line with dialout: and add your user to the end of the line, after a comma with no space, i.e. dialout:foo,your_user. Then, log out of the user and log back in for the change to take affect.

To run Mu on Windows, double-click the icon.

To run Mu on Mac, double-click the icon in the Applications folder.

To run Mu on Linux, from inside the virtual environment, type python3 -m mu into the command line.

Once Mu is opened, it will present a list of options. For this tutorial, choose "Adafruit CircuitPython".

If there is no CircuitPython compatible board plugged in when the editor is opened, there will be a dialog box that starts with "Could not find an attached Adafruit CircuitPython device". This is normal.
