Sharp IR Sensor Obstacle Detection

This is an obstacle detection setup using a Sharp IR sensor, an Arduino, and a small hobby servo. It is based on the project and software found here... http://www.uchobby.com/index.php/2009/03/08/visualizing-sensor-with-arduino-a...

Hi,

did you manage to get a stable reading from the IR sensor?

i'm currently using a couple of the IR sensor but the signal from the IR sensors fluctuates so i tried a different sets of capacitor to the signal output(red right?) and yes it helps. so did you find another solution for this problem?

@ffdxshow It seemed relatively stable, but the measurements I was making were while the servo was panning, so there was some anticipated slop. I never measured with a motionless sensor.

wheagy can u kindly tell me how to control the sensor

and where in the internet i can find the sample programming for it

im using pic18f

@smtkl I'm sorry, buri used the Arduino, so I'm not really sure about the pic. But, there's lots of pic code out there, so a google may be helpful.

hey this is cool, i have one, and i dont know whats wrong with it, but i hooked it up correctly (made sure) and all of the sudden it started to heat up, i think i fried it, but i dont know how, it worked fine for a bit, the readings were stable but then it stopped, its not working but i didnt touch it, what do you think is up?

@wheagy yeah that's right and thanks for your quick reply. it took about 0.5 second to get a stable reading and one more thing i would like to share with you, a low pass filter hook up to this sensor works amazingly well.
