According to #3786 removed the reference to Leonardo only in while(!Serial) of the examples. Changed in in "wait for serial port to connect. Needed for native USB port only"

ASCII table
|
|
|
|
Prints out byte values in all possible formats:
|
|
* as raw binary values
|
|
* as ASCII-encoded decimal, hex, octal, and binary values
|
|
|
|
For more on ASCII, see http://www.asciitable.com and http://en.wikipedia.org/wiki/ASCII

|
The circuit: No external hardware needed.
