Single chip metal detector circuit

-

This circuit is a Single chip metal detector.Actually we can use this one to detect metals.Specially,I think you have seen some army soldiers keep some thing to detect metals.That equipment has been made through this circuit.so you also can use this to detect metals even bombs





Note

# The IC must be mounted on a holder.

# The switch S1 can be a slide type ON/OFF switch.
