Diy Arduino based metal detector. UPDATE: Try using BC547 as transistor people a!e reported problems "it #n####. $e and my son decided to go treasure unting "it a metal detector tat "e a!e but "e couldn%t &ind it any"ere. Being proper ma'ers "e decided tat it "ould be more &un to build one oursel!es rater tan 'eep trying to &ind it. $ost metal detectors uses a searc coil tat act as part o& an oscillator circuit. (en metal is put in pro)imity o& te searc coil te &re*uency o& te oscilations canges. $any metal detectors +including te one "e can%t &ind, uses anoter more stable oscillator B- +beat &re*uency oscillator, to act as a re&erence &or te &re*uency o& te searc coil. Usually te &re*uency o& te B- is ad/usted to e)actly matc tat o& te searc coil oscillator "en no metal is present near tis. Te signals &rom tese t"o oscillators are ten &ed to a0 usually analog0 circuit tat create an output proportionally to te di&&erence in &re*uency og te t"o. Tis may be eiter an audiable tone and1or some meter reading. Anoter de!ice tat are really good at detecting minute &re*uency canges is a microcontroller. (e decided to s"ap te B- approac &or a microcontroller and came up "it &ollo"ing simple circuit:
Te oscillator circuit &eeds a around 23'6 signal to pin 5 o& te Arduino. Te Arduino s'etc ten s'etc ten measures te &re*uency o& tis pin !ery accurately. (en te %U88 9(.% button is eld tis &re*uency is stored. Any de!iation &rom tis &re*uency is ten represented as a series o& %geiger counter% clic's on te pie6o. Te rate o& te clic's increases as metal approaces te coil. (e tried di&&erent searc coils and &ound tat around turns o& "irer around a 25cm. plastic buc'et "or'ed "ell. All "e needed ten "as to tie it all to a discarded ;'ea lamp and ey< presto o&& to te beac to &ind treasures. Te metal detector as e)cellent sensiti!ity and by canging te 9E9;T;=;T> !alue in te Arduino s'etc you are able to tune it &or bot small and large ob/ects. ere is te source code i& code i& you "ant to build one yoursel&. appy unting? 11 Arduino based metal detector 11 +C,D6l /uly #2
