This program prints out a text string one character at a time. Try changing the text phrase.
char myStr[] = "this is a test";
void setup() {
Serial.begin(9600);
}
void loop() {
for (byte i = 0; i < sizeof(myStr) - 1; i++) {
Serial.print(i, DEC);
Serial.print(" = ");
Serial.write(myStr[i]);
Serial.println();
}
delay(5000); // slow down the program
}
