Interesting website: http://arduino.cc/

I'm sure I know less of this than you John but....

It has a section on Hall sensors:

http://playground.arduino.cc//Main/InterfacingWithHardware#Magnetic_Hall

My Digifant pro manual shows that the IS unit uses input from the
distributor hall.

My guess is that PS and AC switch inputs should be "simple" enough for
the right person.  (read: not me  ;)

Would arduino interface properly with the connection to pin 1 of Digifant ECU?
