Arduino Nano Pulse Induction Metal Detector ProjectThis book is intended for Arduino users who have already mastered the basics of programming, and for those who have at least an elementary knowledge of electronics. It is assumed that the reader has progressed beyond the level of flashing LEDs and generally testing various random projects designed to show the capabilities of the Arduino platform, and is now ready to construct something more advanced that will have a real practical use. The project presented here is for a pulse-induction (PI) metal detector with a professional level of performance.
