Hey wayneft!

Found the trouble. The sketch picture was wrong. I used RX0 and TX1 as shown, instead of pin 2 and 3. As soon as I moved wire from RX0 to pin 2, lots of joy, and lots of data on SM. Of course pin 3 is not needed.

What is RX0 and TX1 used for. I really went by the picture which show wires to these pins. Sketch shows const int rxpin = 2;   and   const int txpin = 3;

Onward!  Thanks again...Don



Here is the figure that should have been used in the book. I will correct this on the next edition.
