Project SummaryBuild a RFID Control Box
Use a Phidgets RFID reader to detect tagsUse DPDT Relay to activate electronic strike &
deadboltModify control circuit of electronic deadboltUse laptop to control access to the door

Phidgets RFID ReaderReads tags brought
within 3 inches of the reader
Reads any tag with EM4102 protocol
On-Board LEDBoard connects directly
to a computer’s USB portDrivers and source code
for sample application

ConclusionsCorrect/updated drivers for RFID readerHave the latest library for RFID reader
before compiling your codeBeyond just opening doorTags need to be compatible / same protocol
before they can be recognized by a specific RFID reader
