What am I doing wrong? I thought the FET would be full on when it sees ~ 3V at the gate? What am I missing?
I do not think I did anything... But with a breadboard and wires and stuff... Who knows... I did a search on this error and found a ton of posts about this. Everyone, had a different story on what they did to fix it. Nothing has worked for me... That's because it's a very general error message, just means AVRDUDE can't seem to talk to the board, could be anything hardware like bad usb cable, bad board, etc. Because it can be so many different reasons, there are a ton of I fixed it posting that don't apply to anyone else.However it sounds like the USB converter chip may be working from your description. A full test requires a loop back test. Jump a wire from reset pin to ground pin, then plug board into PC, open arduino IDE, select proper comm port number, open serial monitor. Whatever you type in the send window should be echoed back to the receive window.If that works ok, then you may only have a bad avr processor chip. A replacement 328 chip with bootloader installed can be had for $6 from several sources. I like SparkFun. I know the COM port is working. When I open the serial monitor and type in some text and hit enter I can see the RX light flash. Also, the RX light flashes when I try and up load.Then I read some place that the LED tied to pin 13 should flash after the reset button is depressed. Mine does not. So maybe my bootloader program got wiped?Just get a new $6 328 chip if the echo test works ok.I don't know... I'm almost afraid to order a new board now after seeing all those messages about this problem...Not sure what to do now... :-(Just do it, buy a replacement chip, even if it doesn't solve your problem is useful as a spare or can be wired up as a standalone project.--
No luck... (but thanks for the advice). The RX led shows it receives the send but nothing comes back... I may order the extra chip just to see... Thanks for the help.
Hi Lefty,No luck on the second test either... I ordered a new board tonight. For $20 what the heck. I'm not sure what I did but I fugure I'll give it another go. Besides, i ordered a Motor control shield a few days ago so I may as well get another board. Let me ask you something... When I get this new board do you think I would be risking the chip if I oulled it and placed it on this board not working now? If it worked I could then order a replacement chip. If it did not work then I'm good t go with the new board...Tim--
