First of all, I have to apologize if someone else asked this question on this forum before, because I'm sure they have and I can't find it and I'm gonna get told off, but anyway, here it goes:
I need a proximity sensor. I have not purchased a proximity sensor, but yet I own 2 transducers and several IR leds. I would like to interface either the transducers and/or the IR leds to my arduino, hopefully, without purchasing other components. If this is not possible, then just say so. I've searched for ultrasonic range finders and IR proximity sensors and the like, but I cannot find good information that I understand, you might, but I might not so if you know the answer to my question or you find information and can interpret it for me, that would be greatly appreciated.
Thanks in Advanced
I just need to know what pins to connect either the transducers or the IR leds to, on the arduino, and a little boost on how I might program it, but I should be able to find information about that.[/edit]
