I am putting bumper switches on the back of my bot. I am trying to save on Digital ports so my idea was to use resistors and acd input.
Here is a very crude drawing for the idea I am talking about. What I am wondering is if it will work as I think?
When a switch is closed the acd will read the resistor and I can use the software to figure out which switch is closed.
What do you think. I just want to make sure i don't let the factory smoke out the the EZ-B.
