Arduino wireless metal detector DIY / Spirit PI

Arduino wireless metal detector is a project based on smartphone and an arduino microcontroller.
It is a homemade pulse induction metal detector.
This metal detector is wireless, such as xp deus metal detector.
It is based on the "PI" technology - Pulse induction. The coil detects metal objects and arduino sends the data
through bluetooth module HC-05 to the smartphone. It is easy to do, the coil has only 25 turns.
The components are easy to find. We use an operational amplifier TL072, an irf740 MOSFET,
an arduino and a few more components. In this video I am going to show you
how this metal detector works and when i finish the app
i'll upload it to PlayStore and make a detailed video tutorial how to make this metal detector.
If you are interested, you can subscribe to my channel.
I will also upload the details to my website:
