Read a string by BARRAGAN http://barraganstudio.com
Demonstrates how to read a string from the serial port It is important to use delimiters in the String to read for example read data until a '\n' or a designated character is found This example reads data from the serial and stores into a String variable until an 'L' is found, 'L' will be used as a terminator for the string for testing with the console Send. Change the 'L' for whatever delimitator you might want to use in your strings.

char val; // variable to receive data from the serial port String data = ""; void setup() { Serial.begin(9600); // start serial communication at 9600bps } void loop() { if (Serial.available()) // if data is available to read { val = Serial.read(); // read it and store it in 'val' if (val != 'L') // if not an 'L' { data += val; // add it to the data string } else { // if 'L' was received (our designated termination char) Serial.println("string received: " + data); // print the stored string data = ""; // empty data for next string reading } } }
