hi guys...
my lecturer ask me to design a circuit to detect metal and then will drive the motor... basically i used a coil to put above the robot.. the coil will generate magnetic field and detect the metal that we put under the robot (same as line tracking robot)... then it will drive the robot's motor and make the robot follow the metal that we put under it...
i dont have any idea bout it...
can smeone help me??

what do you mean by "follow the metal" and what size of motor are you talking about?

here you something to get you started it's a good circuit for the metal detector http://www.geocities.com/hagtronics/metal_2.pdf then you just decode the output and use it to turn your robot where you want it to go

Hay I was looking at some old circuits i had made before if you had a metal strip on the floor and you wanted your bot to follow it 2 hall sensors would make it like it's riding a track

Don't you think it would need to be ferrous, with at least one source of a magnetic field on board?
