I have now been working with a IR range detector. But i have tried to find some information on how a sonar work, as some of my firends said that it will be better to use.
Any1 know how a sonar for obstracle/range detection work?
Ok thanks Benbo
If i can get the cash, i might get a SRF10(www.robot-electronics.co.uk), but cost alot here in Denmark. But think it is the best i have found so far, as it is also small, and should be easy to work with. After what i can see on the datasheet.
Hope that i get some extra founds to my project.
And i have some problems with getting the components to make it my self.
Thanks for your repleys.
Just 1 quick question, BoBBy, can you use the sonar to both detect an obstractle, and to measure the distance to the object?
Yeah, that one is kewl, but i use this one's ne555 configuration to make 40khz wave: http://users.encs.concordia.ca/~dave/project/elec.html#Obstacle detection sensor and an lm324 instead of lm358, with 2 Rx, so i get stereo sonar :>
