I have a problem with my brand new Arduino, it seems that no matter what I print with
Serial.println()
be it numbers, strings or anything else, I get garbage on the Arduino serial monitor:
Not even the simplest hello world program works.
Could you help me identify the problem and solve it?
I found the solution :)
I wrote a test program and found a working baud-rate at 600.
My test program:
long baudrates[] = {600,1200,2400,4800,9600,14400,19200,28800,38400,56000,57600,115200,128000,256000};
unsigned char baudcounter = 0;
// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication
Serial.begin(baudrates[baudcounter]);
}
// the loop routine runs over and over again forever:
void loop() {
Serial.println();
Serial.println(baudrates[baudcounter]);
Serial.println(" !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~");
Serial.println();
baudcounter++;
baudcounter %= sizeof(baudrates)/sizeof(long);
delay(1000); // delay
Serial.begin(baudrates[baudcounter]); // switch baudrate
}
