Hello all,
I am doing room automation project with ELECHOUSE Voice Recognition Module V3.
And besides I have very basic knowledge of programing, I got this system to work, but there is 1 problem. But first about the system: I am using V3 module to switch on and off 3 things:
- Room main light (with servo)
- Room night light (with reley)
- Sound amplifier for the music (with servo)
You could wonder why I am using servos and not relays for all that stuff, its because its not my house and i do not want to disassemble main room switches etc... But that doesn't matter. Servos working well in my case, they physically switching on/off other switches.
The problem with V3 module is that if you record sound commands in quiet conditions and near the microphone. Later you have to shout in the room and recognition is quite poor. If you recording commands from about 2m. distance, later recognition is much better, but if you are watching movies o listening music (especially louder) the system goes nuts and recognizes commands then it shouldnt that at least few times in half a hour. What I want to do is simply take 1 voice command for system to listen for lets say 10 sec for other 6 commands (3 on/off switching commands), and after that time system will listen again for that specific 1 voice command. As I said I have very basics of programming, so need your help guys. This is my working code so far and it needs to be a little adjusted, but I dont know how to add this functionality.

I think only one thing with "IF" statment for some time must be added somethere before these commands:
