You can also make your microcontroller have your phone talk out loud using the :TALK: or :talk: command.
For the microcontroller to have your Android phone talk out loud you must include:
See the code example below or visit my website to download more example code files.
// Microcontroller code example
//Change delay times if needed
String inputString ="";
char incoming = 0;
void setup ()
void loop ()
incoming = Serial1.read();
inputString += String(incoming);
//must be exact spelling
if(inputString == "Cool")
//add code here
if(inputString == "Respond")
//add code here
if(inputString == "Talk")
