You can only have one serial monitor running which can be a pain when you want to look at both Arduino and Processing at the same time. So you can only have the serial monitor for either one. Also anytime you want to upload code to Arduino etc… anything using that serial/ COM port needs to be closed.

Ok the serial monitor must be closed. XD

I try your sketch with my code and a maxbotix sonar, but when i play it while the serial monitor is running it seems that the data can´t arrive well, it makes a carriage return in the middle of data arrive. when i stop the sketch the data arrives ok again.

it´s my first approach to Processing, any ideas? what i´m doing incorrectly ?

Thanks and excuse my poor english:)

I think you can modify the servo libraries to do sub degree movement which would the way to go, not sure bout the compass (I haven’t got one!) but it’d be cool to do that for orientation and mapping

I copied and used your code with my JR (MC35) servo… sllooowwwww. If I had an extra $50 laying around, I think it’d be nice to mount a compass module on the USSensor and just have the servo looping 180 back and forth, getting angle and distance readings at the same time. THis should avoid the 1degree then 1degree then 1degree movement. Not sure how fast the compass provides accurate data, though.

Any thoughts on this approach?

Dude, that sounds sweet! I will have to hunt around for that, best i got was an Infrared jobby… I have also been trying to find something to do thermal imaging – but right now I’m workin on plotting 3d stuff instead of the radar screen. But Aliens sensor thing would be sweet if it was real

Looks like the movement sensor from the “Aliens” movie.
Those devices, the way it was explained in the film, implied using some kind of ultrasound that picked up movement, even if the device was stationary, through detection of air movement around a moving object (or creature!!! Hudson!!!!!).

Does such a sensor exist and could it be used for this project?

there you have me bang to rights! It is a sonar, but with a radar style screen/ visualisation – at least to my uneducated senses.

would you believe it! thats exactly what I’m doing – I’m just working out the exponentials for the sharp sensor now, then I’ll update the radar screen to test its accuracy, if that’s all good then I’ll start plotting 3d stuff

Makes you wonder how fast this will be when using a Sharp IR distance sensor like GP2Y0A700 with its ~17ms readout speed. I feel a 3D dome scanner coming up…
