Hi, i need an Ir sensor to avoid obstacle, there are a lot of sharp ir sensors, what is the most popular so that i can found a lot of tutorials and sketch?
i watched there http://www.robot-italy.com/index.php?cPath=15_47&sort=3a&page=2
and there http://www.regaliedesideri.it/hobby-equip/electronics/components/sensors/sharp-ir-rangesensor.html
please help me :)
I got this one from Solar Botics /HVW tech
It worked first time...
I am sure you can find a local supplier.
Did some fiddling with the SHARP 2Y0A02 F 9Y , 20 - 150 cm See article on platyground how to handle - http://arduino.cc/playground/Main/MultiMap
hope this helps
You may also want a sonic ranger for a second way. IR won't work too well under natural sun light and different things reflect IR differently. If you also have a sonic ranger, you will very less likely miss an obstacle when both sensors fail to detect. I use sonic rangers to help me back my car :) It's posted on the exhibition board.
