Using arduino with float switches
hi,
i use float switch in aquarium setup in order detect overflow issues arduino, however, i'm not sure how wiring.
the float switch has 2 wires , if i'm not mistaken, i'm supposed measure resistance using arduino. have experience sort of switches?
many thanks!

i have float switches cost piffling 70c. magnetic on/off switch , therefore work press button on arduino. think might referring probe measures resistance through water, if there there, no float.
