[sudo-discuss] Arduino current protection code?

[Deno Vichas]

tracy,

you can't do it in software. by that time the micro controller already 
got the spike.  (i'm no hardware guru) but i believe you want to either 
put something a diode or resister on that input pin.  but it's hard to 
say without a schematic.

They have a separate power supply, but I'm not using any motor controller.  Does this seem like a bad idea?  Could that little code provide enough protection from current spikes?
