+  Console Pixel
+ 
+ An example of using the Arduino board to receive data from the 
+ Console on the Arduino Yun.  In this case, the Arduino boards turns on an LED when
+ it receives the character 'H', and turns off the LED when it
+ receives the character 'L'.
+ 
+ To see the Console, pick your Yun's name and IP address in the Port menu
+ then open the Port Monitor. You can also see it by opening a terminal window
+ and typing 
+ ssh root@ yourYunsName.local 'telnet localhost 6571'
+ then pressing enter. When prompted for the password, enter it.
