Multiple Line followers

Hi all!!

I wonder if it is possible and how to attach multiple line followers to just one arduino pin so if any sensor is active the arduino detects it.



What do you mean by "line follower"? That phrase usually means the entire robot.

Part number? Link?

If the device you’re talking about sends a signal to generate an interrupt, then you could use some logic gates to route all of these to one pin. The interupt service routine could then actively check them all to find the one that needs attention.
