Hi, I found this link on the WWW.
Is there anything similar already out there within (the reach of hobby folk like me) that could be use with an Arduino? Maybe with a range of say few a cm to a few metres? Tried some of the robotics sellers' websites, but no joy.
Cheers
I am only aware of the ultrasonic ping sensors.
This is a new much more accurate version of the ping sensor that I came across today:- http://www.coolcomponents.co.uk/catalog/ultrasonic-rangefinder-hrlv-p-1068.html
Thanks guys
I'll have a look at those links.
