A simple, good DIY metal detector

Welcome to the channel! Today we'll build a simple yet highly functional metal detector from scratch using just one microchip and wiring. The assembly is very simple and shown in detail. The coil is easy to wind. Setting up the device doesn't require any special equipment; a multimeter is sufficient, but you can get by without one. Enjoy watching everyone!
