Programming for voltage readout through Arduino leonardo and Xbee series 1

Paul,

Thanks a lot. Feel grateful to you for always providing constructive suggestion technically and morally. As you pointed out, the voltage singal I would like to deliver from one-to one Xbee communication system should be ASCII type data, I modified my code.

int myData = 0;   // for incoming serial data
 
void setup() {
         Serial.begin(9600);     // opens serial port, sets data rate to 9600 bps
         Serial1.begin(9600);
         while(!Serial){
           ;
       }
       }
 
void loop() {
 
   while(Serial1.available()>0){
    myData = Serial.print(Serial1.read()); //input from Serial1 to Serial
  }
        // send data only when you receive data:
         if (Serial.available() > 0) {
                 // read the incoming byte:
                // incomingByte = Serial.parseFloat();
   // float voltage =incomingByte*3.3;
                // say what you got:
                 //Serial.print("I received: ");
                 Serial.print(myData, DEC);
                // Serial.println(incomingByte);
         }
 }

The readout from serial monitor pop up window is
