I have to manage servos from a computer.
So I have to send manage messages from computer to Arduino. I need manage the number of servo and the corner. I\'m thinking
It looks like you just need to correct
foo = ''; >>to>> foo = "";
foo += Serial.read(); >>to>> foo += char(Serial.read());
I made also shomething similar..:
void loop(){
while (myExp == "") {
myExp = myReadSerialStr();
delay(100);
}
}
String myReadSerialStr() {
String str = "";
while (Serial.available () > 0) {
str += char(Serial.read ());
}
return str;
}
