This arduino project helps you to build easy a Pulse Induction metal detecter "Spirit PI".
This metal detector is wireless it's based on an arduino microcontroller and android app.
On my YouTube chanel you can fine video tutorials that will help you build this metal detector step by step.
the list of all the components that you will need to find on my website:

It's a project that I have just started, I'm going to improve it and add more options and power. Its operation is quite simple, we have a coil of 25 turns and a pulse generator made with a mosfet and arduino microcontroller. when it detects the metal the information is sent by bluetooth module hc-05 to the app "Spirit PI", in the app the calculations are made and if there is metal under the coil a sound and vibration is emitted in the smartphone.
You can ask me any questions you have. I always answer the questions. If an error appears, I will fix it as soon as possible, just communicate it to me.
All the information and more projects you can find on my website I will be updating as the project grows. My web page:
