Hey, so I'm using the geeetech voice recognition module shown in this video . I want it to tell me in the serial moniter that it knows which commands I'm giving it (I'll add in functions later), but even though I use the same basis of code they use on the website, I still can't manage to get any results. Here's my code can you find any problems with it?
#include <SoftwareSerial.h>

#define PowerOff (0x15) /Group 1/
#define Up (0x16) /Group 2/
#define Down (0x17) /Group 2/
#define Stop (0x18) /Group 2/
#define Left (0x19) /Group 2/

Also, I do receive the "unknown command" sometimes (this is the default response), but it is not reliable. I do have the commands uploaded correctly and on the software I uploaded them on from my computer, it recognizes my commands. I've been working on this for ages, but can't seem to spot the problem so any help would be appreciated.
