I’m rather new to using arduino and i was hoping you could tell me how to include the servo library in the program.

Great tutorial. I’m currently working on a similar project with Parallax PING sensors (3 total), where one is mounted on a server and rotating 180deg at 15deg intervals (11 total), just like you’ve done. The problem I’ve run into seems to be a buffer overflow and automatic reset of the Arduino Duemilanove when I write the 11 sensor values to an array. I’ve been playing with adding delays after each servo movement, which does improve the result but adding some different code eventually causes more problems. With that said, make sure you have enough memory in your board to do what you want or else it’ll crash and reset itself.

Hey Larry,

First of all, good work on this project!
Okay, I am doing this as a project at college, but using PICAXE Programming software. I have a working code and circuit and everything that can find distance in it’s registry. I was just wondering how I would go about creating a radar screen like yours here? and also, do you know how to input data from the PICAXE chip to the PC so it can use the data to map out distance on the radar screen?

Thanks

Good implementation…I’ve been tinkering with this off and on with similar frustrations. From using shipborne radar, usually radar displays image the range of the reflecting surface rather than the extended polar trace of the complete signal as you’ve done, giving a result of objects/surfaces only. Either works, but the former is more intuitive to interpret (and may be easier to interface with robotics).

Larry, have you worked with the SFR10? I have had little luck getting it to reliably read distances of a person moving from 15-20 feet to about 2 Feet. I have built two projects around this sensor one using a Basic Stamp and now one with an Arduino but still can’t get the measurements to read reliably. I need to set 4 zones that when a person moves from one to another it will trigger different segments of the sketch to run. Any suggestions or code examples? If I can’t get it to work I will next try the Sharp IR R316-GP2Y0A710YK sensor.

Thanks for any help to can offer.

it must be the carrots at the ends that hide the line-so for those who are challenged, it should be #include space less than sign space Servo.h space greater than sign. I know this is a dumb way to represent it, but this would have helped me have this running yesterday.

The posted code needs the include line for the servo changed (mising the Servo.h) or else it won’t compile in Arduino. Simple fix.

#include // include the standard servo library

Never tried it, I am intrigues to know if it would work – though dont get the circuits wet!! let me know.

Hats off to you larry. first i thank you for the support you are doing for beginners like me. is it possible to pin point an object in the water with this radar? if so could you give an idea?
