Description
Description
This is a simple metal detector circuit, Can find various metal and adjustable sensitivity Easy to use to place near metal. The circuit inside includes a few components has IC-NE556 is at the heart of the circuit, with a principle of Monostable multivibrator then show on Moving Coil Type Meter. Though very ancient, it still has many uses. Read More : [**Simple metal detector Project**](https://www.eleccircuit.com/simple-metal-detector-circuits/)
