uint8_t inNum = 0;
// Read serial input:
while (Serial.available() > 0) {
int inChar = Serial.read();
if (isDigit(inChar)) {
// convert the incoming byte to a char and add it to the string:
inString += (char)inChar;
}
// if you get a newline, print the string, then the string's value:
if (inChar == '\n') {
Serial.print("Value:");
inNum = inString.toInt(); //<<< Itt a kapott szám
Serial.println(inNum);
Serial.print("String: ");
Serial.println(inString);
// clear the string for new input:
inString = "";
}
}
Még ma megnézem mi is ez.
