Simple ReadWrite
Read data from the serial port and echoes it back to monitor it in the console

    char val;                   // to read the char

    void setup() {
      Serial.begin(9600);
    }

    void loop() {
      if(Serial.available()) {  // if data available
        val = Serial.read();    // read data
        Serial.print(val);      // print it back
      }
      delay(100);               // wait 100ms for next read
    }
