I understand pull-up and pull-down resistors used with switches to detect input but I want to go a step further.

 

Can someone point me in the right direction getting the BS2SX to detect when an external circuit is on?

 

I would like to be able to program my BS2SX to see when an electromagnet has been energized from a separate circuit and then execute my program.

 

Thanks electroheads!

 

Cheers
