I am new to pd

I am making a speech controlled wheelchair as my final year project . I am planning to use Simon and Arduino for the project with Pd .

I am having problem in connecting Simon and Pd . The desired output is that whatever command is given to computer through mike should be send to Pd.

Please someone help me.

how can simon output?
OSC would be ideal for pd, but there is a lot of software to convert something to osc also.
