"Spirit PI" Wireless Metal Detector | N.E.C.O

"Spirit PI" is a pulse inductions metal detector. This metal detector is based on an Arduino or ESP32 microcontroller and a smartphone. It is easier to make than a VLF metal detector because you do not need to adjust the coils and adjust the balance of the coils. In this metal detector we only use one coil that at the same time is the ...
