I wanted to make an easy and secure way to enter my garage. RFID was theest way to un!ock my door" e#en w$th my hands %u!! I can un!ock the door andpush $t open& I u$!t a s$mp!e c$rcu$t w$th a as$c '()ega 18 ardu$no ch$p and aID+20 RFID reader to contro! an e!ectron$c door !ock.

(he c$rcu$t cons$sts o% , separate parts" a Reader to read RFID tags" a -ontro!!erto accept data %rom the reader and contro! the output o% the R D and the!ectr$c door !ock. (he door !ock $s %$rst $nsta!!ed $n a door and tested w$th a 9#attery to ensure correct $nsta!!at$on. In most cases you want a orma!!y 3penc$rcu$t on the door !ock" or Fa$! 4ecure. (h$s means the door stays !ocked whenno current passes through $t. 5hen 12#D- $s passed through the e!ectromagnet$n the door !ock" a p!ate $n the !ock g$#es way and a!!ows the door to e pushedopen %ree!y.

(he reader $s p!aced on the outs$de o% the door and $s separate %rom thecontro!!er on the $ns$de so that no one can c$rcum#ent the secur$ty y reak$ngopen the Reader and try$ng to short c$rcu$t the reader. (he contro!!er rece$#esser$a! data %rom the Reader and contro!s the R !ed and the Door !ock. In th$scase I ha#e put oth on separate read oards %or test$ng. 6ere $s a #$deo

I wanted to use on!y RFID to contro! the operat$on o% the c$rcu$t as we!! as contro!o#er the door !ock.
