Much better, the IR sensor has a about a 7deg divergence, ultrasound is much higher (more than 30deg). The problem with the IR sensor is when you use a couple of them together, there is a minimum distance of about 10cm that you need to keep between them (for ranges around 1-2m). Wiki has a good summary of the pros-and-cons.

Hi, how much better is the ir sensor then the ultra sonic ranger finder(parallax?)?

Hi Toma, thanks for commenting! There's a link for the source code at the bottom of the article or you can click here. Just paste it into the Arduino environment.

Hi there. could you email me the code for this project. I’ve secured most of the parts and am anxious to give this a go. thanks!

Thanks for the comment! The PC is only used to supply 5V – once coded up it’s completely stand alone. You could even run it from a 9V battery without too much trouble. For the greater good, well, we can all have secrets!

Even I can follow this one (what a novelty!) – but one question still nags: what’s the ‘greater good’ for this project? (your first sentence) Do you need a PC to trapise along behind or is it standalone once the chip is coded up?
