How to use py_arduino.cli.* after install

You can start using py-arduino from the command line interface (cli) without actually writing Python code (see the reference for furder information). There are scripts to:

• ping: Check the connectivity to the Arduino
• ipython: Start an IPython interactive session
• analog_read: Reads the value from the specified analog pin
• analog_write: Writes an analog value (PWM wave) to a pin
• digital_read: Reads the value from a specified digital pin, either HIGH or LOW
• digital_write: Write a HIGH or a LOW value to a digital pin

To use these scripts, you need to:

• activate virtualenv,
• setup PYTHONPATH environment variable.

Virtualenv

You must activate the virtualenv to use py-arduino, using something like:

source /path/to/py-arduino/virtualenv/bin/activate

or

. /path/to/py-arduino/virtualenv/bin/activate

(note the space between the . and the path to activate).

After activating the virtualenv, your prompt will chage: a (virtualenv) will be prepended.

PYTHONPATH

If you cd to the py-arduino directory, you won't need to set the PYTHONPATH, the scripts just works:

If you want to run py-arduino from other directories, you'll have to set PYTHONPATH:
