ultrasonic sensor

Can I unsolder the transducers from the Parallax PING sensor and replace them by these ones: http://www.parallax.com/Store/Sensors/ObjectDetection/tabid/176/ProductID/755/List/0/Default.aspx?SortField=ProductName,ProductName? They operate at the same frequency. Also, why does the PING sensor have two transducers? I guess one is a transducer and the other is a receiver, but is it the same part?

I have (that is relative because I have not yet ordered my first parts from Robotshop) a PING ultrasonic sensor. I'll be having an arduino mini - though I'll no doubt buy something bigger after - and I wonder if I can efficiently make my upcoming rover (differentially driven, nothing special really) map it's surrounding area using a grid. Is it possible or will I run short on memory with the arduino mini? And more importantly, I need help with the code (I have 0 experience with code, though I have enough theory I guess...). Any suggestions are appreciated.

Hi,

I have this ultrasonic sensor, it's from a part of a Cybot. I was wondering if anyone's used one of these on a Picaxe and if so, did it work?

It's a 9v part, so I'm unsure if it will work on Pcaxe.

I'm trying to understand this sonar-board from my old cybot robot, but I think I will need a little help :

- If I'm correct I should put a voltage on the transmitter sensors for a short period of time (100 ms?), then read in the value of pin 2 and 3, right?

- What voltage should the transmitters get? 5V?

Anybody please tell me how to interface this sensor with arduino, i planning to create a obstacle avoiding robot using two dc motors and a servo with this sensor.

Please help me with programming and circuit...


Thanks,
