Alright so I jumped into a project, I have the case made, parts put it, organized and soldered and am programming it however there is a hiccup. I need to run two ultrasonic sensors. It seems like it should be easy enough but they are not working for some reason.
I am using newping as my sensors have separate trig and echo pins. I used the original tutorial pins 12 and 12 on an arduino pro mini and it worked fine. For the project to make it more organized I used pins 6 - 9 for the ultrasonic sensors however now they read 0cm unless i tough a wire, then they read around 150cm.
So, what is going on? I figured they would work on any pins. 11 and 12 are digital pins, are they not? Do I need to move these over to pins 10 - 13?
