Title
Body
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 of sendin something like this : "1;130" (first servo and corner 130, delimeter ";"). Are there any better methods to accomplish this? Here is my this code : String foo = ""; void setup(){ Serial.begin(9600); } void loop(){ readSignalFromComp(); } void readSignalFromComp() { if (Serial.available() > 0) foo = ''; while (Serial.available() > 0){ foo += Serial.read(); } if (!foo.equals("")) Serial.print(foo); } This doesn't work. What's the problem?
