I powered the dc motor (it was the kind you get in toy cars) with 9v and now it is nto working, any ideas on wahts wrong?
What voltage did the batteries in the toy car originally provide?
(Or to put it another way, what voltage
is was the motor supposed to get?)
And if you are trying to use a little rectangular 9V smoke alarm battery it will almost certainly be too weak to run a motor properly (or at all).
crap just realised it was 3v to 6v :o
