I'm trying to get a ultra sonic sensor which I've wired up through an arduino to work in Max. I know it works as the tech at uni got it working today, I think I'm doing everything he showed me but I guess I'm not as I cant get the sensor to be picked up through max. Could someone tell me what I'm doing wrong? Heres what I'm doing:

The Arduino is all wired up and plugged in correctly, I open up Max I have a Maxuino patch, I select the usbmodem port I select analogue pin 4 as that is where it is plug in but I'm getting nothing?

Arduino Ultra Sonic Sensor can't get to work in Max
