Hi,

Analog shows what sort of data? Readable text...hex...asci?

THanks

None, it's just an analogue voltage - according to the datasheet I posted the URL for, from 0.6V to 3.1V (from my memory). You could read this voltage using one of the analogue to digital converters in a 16F877, this will give you a 10 bit number - from 0 to 1023, representing 0-5V, assuming you use the 5V rail as the A2D reference.

Hmm,

I think Im going to wait until i get my actual kit before asking any more questions so i can better understand how the PIC works.

Ill keep you updated on my progress.... Thanks for your help.

If you've already got the sensor, stick a voltmeter on the output - you should be able to see the reading change as you move an obstacle in front of it.

No i dont have it yet

The people who sell the ice breaker kit said it would be very hard for me to put together with no soldering experience ( which i dont have ) and that I would need help.... any ideas?

Thanks

If you've no soldering experience everything starts to look rather more difficult

Whereabouts are you?, I'm sure there's plenty of people on here who would be willing to help you put it together - I would, but you may be able to find someone more local.

But you really need to learn to solder, I would suggest buying simple kits and building them - my daughter has built a number of Maplin/Velleman kits - mainly flashing LED ones. She started with a flashing christmas tree when she was about 10 years old, she's probably made 5 or 6 kits now, and is a reasonably competent solderer (I wouldn't guarantee the spelling of that last word! - it doesn't look right somehow!) .

Heh spelling isnt important if i know what you mean :P

Yea I agree I need soldering experience, of course I did a tiny bit when I was at school but that was really really basic. Im in Essex so if anyone fancys a new friend

I dont mind doing the kits for the soldering experience but I see 'electronics' without any 'brain' a little boring. Ill look on maplins site for a few starter kits
