RIDDICK:
then u can just use analogRead()..
when it reads 0 no removable station is connected...
when it reads x (x>0) then a removable station with resistance Rremo=(Vref-Vsen)/Isen (where Vsen=(x*Vref)/1024 and Isen=Vsen/(10kR))...u can configure Vref via this:
analogReference() - Arduino Reference
Ok so if I set Vref to 5v and instead of a 10K known resistance I have say a 3.3K would that work?
