Hi! Can anyone please help me identify the problem on my code. I am trying to do basic control with 3 LED using my voice recognition module V3 and Arduino UNO. I successfully trained and loaded my voice commands on the module. However, when I test it out, only the green LED is turning on and the 2 other LED is not. I am sure that my LEDs are working. Here's my code:
#include <SoftwareSerial.h>
#include "VoiceRecognitionV3.h"
/**
Connection
Arduino VoiceRecognitionModule
2 -------> TX
3 -------> RX
*/
VR myVR(2,3); // 2:RX 3:TX, you can choose your favourite pins.
uint8_t records[7]; // save record
uint8_t buf[64];
int green = 5;
int yellow = 6;
int red = 7;
#define go (5)
#define wait (6)
#define stopp (7)
/**
@brief Print signature, if the character is invisible,
print hexible value instead.
@param buf --> command length
len --> number of parameters
*/
void printSignature(uint8_t *buf, int len)
{
int i;
for(i=0; i<len; i++){
if(buf[i]>0x19 && buf[i]<0x7F){
Serial.write(buf[i]);
}
else{
Serial.print("[");
Serial.print(buf[i], HEX);
Serial.print("]");
}
}
}
/**
@brief Print signature, if the character is invisible,
print hexible value instead.
@param buf --> VR module return value when voice is recognized.
buf[0] --> Group mode(FF: None Group, 0x8n: User, 0x0n:System
buf[1] --> number of record which is recognized.
buf[2] --> Recognizer index(position) value of the recognized record.
buf[3] --> Signature length
buf[4]~buf[n] --> Signature
*/
void printVR(uint8_t *buf)
{
Serial.println("VR Index\tGroup\tRecordNum\tSignature");
Serial.print(buf[2], DEC);
Serial.print("\t\t");
if(buf[0] == 0xFF){
Serial.print("NONE");
}
else if(buf[0]&0x80){
Serial.print("UG ");
Serial.print(buf[0]&(~0x80), DEC);
}
else{
Serial.print("SG ");
Serial.print(buf[0], DEC);
}
Serial.print("\t");
Serial.print(buf[1], DEC);
Serial.print("\t\t");
if(buf[3]>0){
printSignature(buf+4, buf[3]);
}
else{
Serial.print("NONE");
}
Serial.println("\r\n");
}
void setup()
{
/** initialize */
myVR.begin(9600);
Serial.begin(115200);
Serial.println("Elechouse Voice Recognition V3 Module\r\nControl LED sample");

pinMode(red, OUTPUT);
if(myVR.clear() == 0){
Serial.println("Recognizer cleared.");
}else{
Serial.println("Not find VoiceRecognitionModule.");
Serial.println("Please check connection and restart Arduino.");
while(1);
}
if(myVR.load((uint8_t)go) >= 0){
Serial.println("go loaded");
}
if(myVR.load((uint8_t)wait) >= 0){
Serial.println("wait loaded");
}
if(myVR.load((uint8_t)stopp) >= 0){
Serial.println("stopp loaded");
}
}
void loop()
{
int ret;
ret = myVR.recognize(buf, 50);
if(ret>0){
switch(buf[1]){
case go:
digitalWrite(green, HIGH);
delay(2000);
