Jlawler:
It's on a sensor bar which has a total of 5 of these pairs. Each input is attached separately to my board....
Jlawler:
Luckily I'll only be using 3 inputs.
I'm curious as to how you plan to connect five sensors to three inputs?
Jlawler:
So my research tells me I should use analog read
Those sensors are open-drain output, so you won't use analogRead.
Jlawler:
but that would only tell me what it is, it won't tell my robot what it is.
This doesn't make sense.
