The Wiegand interface is a de facto standard commonly used to connect a card reader or keypad to an electronic entry system. Wiegand interface has the ability to transmit signal over long distance with a simple 3 wires connection. This library uses interrupt pins from Arduino to read the pulses from Wiegand interface and return the code and type of the Wiegand.
The following are needed
Arduino Mega 2560 Any compatible board should work.
Wiegand RFID Reader.
Reader 1 :
DATA0 of Wiegand connects to Arduino PIN 2 DATA1 of Wiegand connects to Arduino PIN 3
Reader 2 :
DATA0 of Wiegand connects to Arduino PIN 21 DATA1 of Wiegand connects to Arduino PIN 20
Reader 3 :
DATA0 of Wiegand connects to Arduino PIN 19 DATA1 of Wiegand connects to Arduino PIN 18
Installation Follow the instruction for library installation in Arduino.cc web site.
REV 2.0
Bug fix on reader 3
Add the possibility to select which gate need to be active passing parameters to : wg.begin(GateA, GateB , GateC);
Library come from original library developed from http://www.monkeyboard.org
