How do you get a ping proximity sensor to be read in Max MSP through arduino?

Hi community, my name is Martin

I have a project I'm working on in which I need information from a Ping proximity sensor, to go through an ardunio control board which is to be read by MAX MSP. (my project involves linking proximity to a video element)

so, How do you get a ping proximity sensor to be read in Max MSP through an arduino control board?

thanks for your help, I could really do with an answer ASAP
