Serial.readString () inherits from the Stream utility class. Instead you would need to use alloca to perform the same function: char *buf = alloca (vst.length ()+1); However, the way you're doing it is wasteful. Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Serial.readString () accumulates the input chars in an internal String and consumes more heap memory as more chars arrive. 1 You need to use Serial.readStringUntil ('\n') instead of Serial.readString if you use the Arduino IDE's serial monitor (where a \n is added as termination character when you press enter). It may be a little difficult to remember Morse code and convert texts to this code, so let’s make a translator to convert texts to Morse code!
