SurferTim:
Are you planning on using shiftOut? You don't need D10 for that.

I was able to get this all going very well with your assistance. I have attached where I am for the moment, but I have another question.

This sketch is for a weather station and this will be a slave Nano controlling the output to the weather and message portion of the project. While I was able (with the assistance of those present) to move a short message via serial from the master to the slave, I need help getting 'chunks' of data.

I would like to get the Weather, OutsideTemp, InsideTemp,Units, and MessageFlag in a format with which I can decode it and make it work for my sketch. Something like:

$A,-3,72,F,1#

$ = start of transmit
A = char
-3 = int
72 = int
F = boolean
1 = boolean

= end of transmit

I'm using this for the weather, but I can only retrieve a single char, experimenting with variable types has gotten me nowhere.

void loop()
{
  //
  //GO get Temp and Weather
  //
   if (Serial.read() == '

    delay(10);
    {
      Serial.print(Message[MessageLength]);
      delay(10);
    }
    Serial.println("/");
  }
    switch (Message[MessageLength])
    {
      case 65://an "A" was sent
        Serial.println("Sunny");
