softwareSerial Question

Hello all,

I am trying to implement a software serial situation, as my project requires the computer serial interface as well as an arduino - arduino interface as well.

I have been able to follow the tutorial and get the software serial to “echo” the computers serial input, but beyond that I have had difficulties. I need it to form multiple multidigit numbers. Which I have done this way before but just with the computer to Serial communication.

The premise of this basic code, is to take a two digit input (13 of instance) followed by a closer “/” (in a version just using the computer, I am inputting data in a “/” separated manner 10/14/2/ etc)
But this basic testing purposes “13/” is the data I wish to send and do stuff with. Next I will expand it to do two numbers, etc.

can you guys take a look at the following, and perhaps figure out what i’m missing? Their has to be some difference in how the software serial works, that i am not understanding.

This code is on each arduino.

// include the SoftwareSerial library so you can use its functions:
#include <SoftwareSerial.h>

#define rxPin 11
#define txPin 10
#define ledPin 13

// set up a new serial port
SoftwareSerial mySerial =  SoftwareSerial(rxPin, txPin);
byte pinState = 0;

void setup()  {
  // define pin modes for tx, rx, led pins:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  pinMode(ledPin, OUTPUT);
  // set the data rate for the SoftwareSerial port

void loop() {
      byte data =;
  int index = 0;
     byte myserialdata=0;
     byte myserialState[1];

     if(index < 1){
     byte inbyte =;
     if (inbyte > 0 && inbyte != '/'){
        myserialdata = myserialdata * 10 + inbyte - '0';
     if (inbyte == '/'){
        myserialState[index] = myserialdata;
        digitalWrite(myserialState[1], HIGH);
        myserialdata = 0;

Thank you for any assistance.
Thank you for your help
