I received my first Arduino today (An Arduino Uno Rev 3). I have downloaded the Arduino 1.0.5 software and have connected the board to my Mac. I then tried to upload the Blink sketch from the example files. I get an error "avrdude: stk500_recv(): programmer is not responding." I have checked the settings of the software and I have the correct board and port selected. After quite a bit of frustration, I tried the same process on my PC. On that computer, I receive an error also, though it is different. The error reads "avrdude: stk500_getsync(): not in sync: resp=0x00."
At this point, I am pretty much lost. This doesn't seem like rocket science, yet I can't seem to complete a simple task. I went through the troubleshooting guide (http://arduino.cc/en/guide/troubleshooting#toc1) and have tried everything they suggested. The part about the bootloader is the only part that confused me. When I press reset, nothing happens. The on LED stays solid lit as does the 'L' LED.
Did I get a defective product?
Thank you for your help.
