IR Distance sensor
Hi. I have a quick question. This might be sound silly to some of you
but I am little bit confused. So I just wanted to make sure.

In this attachement, there are two sets of IR sensors. Right now, I have
my IR dist sensors connected on the bottom picture. But could I connect my
IR dist sensors as shown on the top picutre??

Re: IR Distance sensor
yes u can. but i think that ll be meaningles cos you ll give the same result to output 1 and 4. u ll be using same comparater port. 2 ir sensor makes sense cos differnet levels of signal makes distance comparable. so if you connect second sensor to pin 10 that ll ok.(also disconnect sensor 1 from pin 10)

good luck
