"Make absolutely sure that you’re using pin 13! If you connect the LED to any other pin, it will probably be destroyed. The reason is that pin 13 has an internal resistor that the other pins don’t have (you’ll learn more about this in Chapter 3, Building Binary Dice,on page 43)."
The above quotation from page 20 (PDF) is incorrect. The last Arduino version to have a series resistor between the microcontroller and pin 13 was the NG. On all newer versions Diecimila, Duemilanove, Uno, etc.) pin 13 is connected directly to the microcontroller. This incorrect explanation is repeated on page 47.

The image of the items needed for the "binary dice" project has a 6 in it twice, once for the resistor, and once for the wires. The reason I noticed this, is I was looking for a picture of the (optional) number 9, "tilt sensor", as I am not sure what one looks like.
I am still not sure what it looks like, so please add a link to an image of one would be greatly appreciated.--Jason Zimmer

#48837: The phrase "For a binary die" should be "For a binary dice".--Michel Graciano
The above erratum cannot be correct. The text should either be "For binary dice" (plural) or "For a binary die" (singular).
The erratum says that this was corrected in v.4.0.

In method Telegraph::output_symbol() at the end of the function there should be a delay(length) so that there is a gap between the output pin going low and the next time it goes high at the start of the next dit or dah. (I found this bug by inspection of the code in the pdf, not through running the code.)--Anon
