Metal detector circuit electronic project using transistors

This metal detector circuit electronic project is an very simple circuit that is based on common electronic parts. This metal detector circuit electronic project is based on transistors and will provide an visual indication using a LED and an acoustic sound that will inform you when a metal is detected. You must turn RV2 potentiometer fully cloc

kwise and RV2 potentiometer anti-clockwise. With SW1pressed you must turn RV1 anti-clockwise until the LED is about to light and all further sensitivity adjustments should now be done by turning RV2. To set maximum sensitivity, turn RV2 until the LED is weakly lit. The brightness of the Led indicates the distance and the size of the metal object detected.
