Hello there all! I have tried experiment, which was sucessful. I made project about control our boards with voice. If you use voice-to-text app, for instance Webkit, you should save your voice to text and to text file and then read it with boards. This is only first demo. I am working on IoT home, i will publish it soon. In the tutorial you can see basics, PHP downloads and demo .ino download for NodeMCU. Also it is simple to make similar code for Arduino. Thanks a lot. My website, where you can donate me: https://arduino.php5.sk
