@Bob... to be honest I don't think it's possible... Not the HC SR04 anyway... These can Maxbotix Range finder , however...

OK that explains it, maybe I'll try the another type I have that I got from Radio Shack. It only has 3 pins so maybe I can hook it up like my PIR to an ADC port.

Here is a ping (that works with the ezb4) that only uses one digital port... Price isn't bad and performance is similar to the SR04... inexpensive ping

@bhouston you'll need to use a digital port for the Parallax PING sensor (the one from Radio Shack) or 2 digital ports for the one from EZ-Robot (the HC-SR04). These are not designed for use on a ADC port.

Are you just experimenting, or have you ran out of digital ports?

@Richard R Thanks, That one is the same as the one from Radio Shack. Your new winnings should help you but some more EZB stuff. Congrats

@JustinRatliff, Yes, I have run out of digital ports. I'll have to get another v4 connected to my project.

@Bob... thanks... LOL... Can you use a sharp IR sensor instead? It uses analog....

Thanks Richard, I'm going to connect a second v4 to my project and that will give me all the digital ports I need. Do you know if there is a tutorial somewhere on running two boards? I've got them both connected but trying to find how to add a servo to the second board.

ping me on skype @bhouston.. I can help with the hook up
