Selecting the Blink example in the Arduino IDE.
7. Press the “Upload” button to compile the sketch and upload it to the A-Star. If everything goes correctly, you
will see the message “Done uploading” appear near the bottom of the window. If you are using Windows and
you have not previously programmed an A-Star on this USB port, then Windows might take several seconds to
recognize the A-Star bootloader. The bootloader times out after 8 seconds and goes back to running the sketch,
so the upload might fail if Windows does not recognize it quickly enough. If this happens, try again. If you are
using Windows XP and have not programmed an A-Star on this USB port, you will have to go through the Found
New Hardware Wizard again as described in
, but the second time you try to upload it should work. If
the Arduino IDE has trouble connecting to the port or using it, try unplugging the A-Star, closing any programs
that might be using the serial port, restarting the Arduino IDE, and then plugging the A-Star back in.
