Good day

I am quite new to coding so please be patient

I need to know how/if i can connect 6 speed sensors to a uno32.

From what I have figured out so far is that it only has 5 interrupt pins.

Is there any workaround for this as in future i might need even more for projects.

How responsive do you need the interrupts? There are 5 "hardware" interrupt pins, yes, but there are also a number of "change notification" pins. These act like interrupt pins, but instead of them being triggered in hardware by by the signal's edge, they are polled by the clock and a detected change causes an interrupt to trigger.
