These directions don't appear to be universally applicable - specifically to the Micro and Leonardo correct?  If not how to?

They are universally applicable to boards that have USB-to-serial converters.

The instructions will not work for a Micro or Leonardo.

How to what?

The sticky test was developed to be able to test just the functionality of a on board USB serial converter chip, independently of the AVR controller chip being used on the board, for boards that have separate USB and controller chips. On boards that use a AVR controller chip that have built in USB connectivity there is no need for this test.

I did it. It worked (eecchhoo)
I`m having a: "avrdude: stk500_recv(): programmer is not responding" with a NKC Freeduino V2.2 on Ubuntu Studio 13.04
Thanks for the tip. Now I know my serial rig over USB is working.

Did not understand setup #7 "Connect the terminal application to the serial port of your board"  I was using Sketch.....Serial Monitor.

Serial Monitor is a terminal application.  It will work fine for the test.

Is there a loop back test for the Arduino Mega 2560? I don't see a reset pin on it. My tx1 and rx0 are on two different sockets. Unfortunately rx0 is on the ftdi that I use to connect to my PC.

"Start your favourite terminal application.  Serial Monitor will work fine."
What would be a terminal application and how do I monitor the Serial Monitor on the Mega 2560?

I also have a Arduino Uno that I uploaded a sketch to and I ran fine so I'm assuming it's working ok. Does this loop test tell me more about my Uno that I would like to know? I have a reset pin and a tx1 and rx0 on the Digital pins. But again, not to sound stupid but what would be a terminal program and how do you hook up a serial port to test with.

The loopback test is to verify operation of the USB/serial chip. If it works there is no need for it
Avoid throwing electronics out as you or someone else might need them for parts or use.
Solid state rectifiers are the only REAL rectifiers.
Resistors for LEDS!

Are you referring to a Mega 2560 board?

According  to the instruction, my PC even  cannot connect my leonardo device . my PC can not find the serial port .PC have no sound(my PC speaker turn on)

its not working ..what should  do?
