Wiegand 26 and Wiegand 34 library for Arduino

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.

Requirements

The following are needed

Arduino uno / Mega 2560 Any compatible board should work following the interupt pin assigment :

Board Digital Pins Usable For Interrupts
================================== ==================================
Uno, Nano, Mini, other 328-based 2, 3
Mega, Mega2560, MegaADK 2, 3, 18, 19, 20, 21
Micro, Leonardo, other 32u4-based 0, 1, 2, 3, 7
Zero all digital pins, except 4
MKR1000 Rev.1 0, 1, 4, 5, 6, 7, 8, 9, A1, A2
Due all digital pins
101 all digital pins
WeMos_D1, WeMos_D1 mini,NodeMCU all digital pins
ESP8266 all digital pins

Wiegand RFID Reader pin connection Example :

for ARDUINO UNO :

    Reader 1 :

    DATA0 of Wiegand connects to Arduino PIN 2 
    DATA1 of Wiegand connects to Arduino PIN 3

    Reader 2 : NOT USED

    Reader 3 : NOT USED

for ARDUINO MEGA2560 :

    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 3.0

Adding compatibility to all the arduino board

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
