Are you certain you have the six-pin cable correctly connected?
The controller has a yellow LED that flashes when it receives from 5V Vcc (more or less). when the Arduino is running normally, the reset pin has a voltage of 5V, but when I press the reset button, this pin indicates 0V.
When I plug in the 6-pin connector, I press the reset button, if the LED
yellow is still blinking, it means it is connected properly. however, if not blinking, it means that I have reversed the sense of connection!
Yes. You type the command (or copy-and-paste it) into a "dos prompt" (a command-shell). The command shell can be started by running "CMD".
You will either have to navigate to the folder containing AVRDUDE or modify the PATH. These update the PATH on my computer so I can run AVRDUDE...
set PATH=%PATH%;C:\Arduino\arduino-0022\hardware\tools\avr\utils\bin
set PATH=%PATH%;C:\Arduino\arduino-0022\hardware\tools\avr\bin
set PATH=%PATH%;C:\arduino\arduino-0022\hardware\tools\avr\etc
Replace "C:\Arduino\arduino-0022" with the Arduino root folder on your computer.
