ping

OK I have re-writen my code and now I am having a problem where my left side motors are not being driven.I know it is not a hardware problem. I upload an older version of code with out the scanning portion and everthing works.I have included LEDS on the proto board to see if I am getting comands from my uC and right side is working but not getting anything for the left. the new code is basicly an addition to the old. I just added the servo and varibles so it can look left and right.

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.

Oh hello there! I'm pretty new with robotics and all of that exciting stuff. I'd been wanting a microcontroller for a few years, and when mbed gave out free mbeds, (yay) I got one and messed around with it a bit.

hi i have got a ping sensor , arduino duemilanove and a motor h bridge how ever i need help programming i need the sensor to tell the motor to turn when it gets too close say 5cm close to a object

thanks for all the help

I just got my parallax ultrasonic distance sensor (#28015) and I have the "test code" running as I type, but how do I use it to warn my robot of walls?

P.S I am using an Arduino diecimila.

I just picked up a Parallax Ping distance sensor from my local Radio Shack and am trying to figure out to how hook it into my Picaxe 18 project board.

The ping uses a single pin for both input and output.  It first requires a trigger pulse to be sent and then it responds with a variable length pulse that determines the distance.  Can a Picaxe pin be switched from output to input?  If not, can I connect 2 pins to the single Ping pin?  Normally I would jut go ahead and try it, but I don't want to fry my Picaxe or the sensor.
