});
sensor.on("ready", function(){
sensor.read()
.ok(function(id){
console.log("Fingerprint found! ID",id);
})
.fail(function () {
console.log("Unknown fingerprint");
})
.wait(function(){
console.log("Put fingerprint");
});
});
Serial Ports
var FingerPrint = require("zfm20"),
sensor;
sensor = new FingerPrint();
sensor.ports(function(port){
console.log(port);
});
