Hi, I'm quite new to the voice recognition project. For this project, I'm going to set the 6 digit of password. So, once the password was matched, the storage locker will open and close accordingly. The problem is that this voice recognition module v3 only can recognize 7 digit at one time. So, I have digit 0 to digit 9, totally 10 digit. So, I have trained the voice module to recognize digit 0 to digit 9. Similarly, I have utilize the multicommand example given in arduino. The working principle is that after I speak from digit 0 to digit 6, I need to set a digit in order to switch to the second group and enable the digit 7,8 and 9 to be spoken. My question is that how I going to set the module in roder for me to speak from digit 0 to digit 9 unsequncely. Below is the code:
In this case, I'm using digit 0 as the word to switch between group1 and group 2.
#include <SoftwareSerial.h>
#include "VoiceRecognitionV3.h"
