hi there, please help ..
I want to make a finger print with selenoid when entering the room and when leaving the room.
I use Arduino Uno V3 by making parallel finger print sensors.
How to combine two SoftwareSerial ?
and when i upload :
Found fingerprint 2 sensor!
Sensor contains 1 templates
Fingerprint 2 is ready to use,
Type 98 to register new fingerprint template
Did not find fingerprint sensor 
//this is finger print lock door
#include <Adafruit_Fingerprint.h>
#include <SoftwareSerial.h>
// consts
const int USERCMD_REGISTER_FINGER_1 = 99;
const int USERCMD_REGISTER_FINGER_2 = 98;
const int PIN_SOLENOID_LOCK = 5;
SoftwareSerial mySerial1(2, 3);
Adafruit_Fingerprint finger1 = Adafruit_Fingerprint(&mySerial1);
SoftwareSerial mySerial2(8, 9);
Adafruit_Fingerprint finger2 = Adafruit_Fingerprint(&mySerial2);
int userCmd;
int scannedFingerId = -1;
void setup() {
Serial.begin(9600);
delay(100);
// set pin for solenoid lock
pinMode(PIN_SOLENOID_LOCK, OUTPUT);
// set the data rate for the sensor serial port
finger1.begin(57600);
finger2.begin(57600);
bool finger1Exist = finger1.verifyPassword();
bool finger2Exist = finger2.verifyPassword();
// check finger sensor 1
if (finger1Exist) {
Serial.println("Found fingerprint 1 sensor!");
finger1.getTemplateCount();
Serial.print("Sensor contains "); Serial.print(finger1.templateCount); Serial.println(" templates");
Serial.println(F("\nFingerprint 1 is ready to use, \nType 99 to register new fingerprint template"));
}
// check finger sensor 2
if (finger2Exist) {
Serial.println("Found fingerprint 2 sensor!");
finger2.getTemplateCount();
Serial.print("Sensor contains "); Serial.print(finger2.templateCount); Serial.println(" templates");
Serial.println(F("\nFingerprint 2 is ready to use, \nType 98 to register new fingerprint template"));
}
// halt when one of finger sensor !exist
if(!finger1Exist || !finger2Exist){
Serial.println("Did not find fingerprint sensor :(");
while (1) {
delay(1);
}
}
}
void loop()
{
delay(50);
