New to arduino but have a deep background in electrical and some in PLC.
I would like to implement an arduino board to detect the pulse of a limit switch that triggers a countdown.
If that trigger does not occur within 60 seconds then change the analog output from high to low.
Purpose of this project would be to alarm out a machine that stops moving after 60 seconds.
If anyone could provide some links or references to get me started, much appreciated.
Likely I would use a relay to send state to a 24v input. Feel free to correct me as I am new.
