avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt one of ten: not in sync: resp=0x00

Is this some kind of joke? Who is AVR Dude, and what does he have against me trying to upload a sketch to my Arduino? If you're getting this error when trying to upload lawmaking to your Arduino lath – it tin can be REALLY frustrating!

I wish I could say this happens because of one single problem – but this error pops upward for many reasons… In this lesson we are going to go through a "laundry listing" of possible solutions. We'll start at the most common and easiest, and move on to more than detailed troubleshooting tasks if those don't work.

By the end of this lesson, AVR Dude should be hitting the road, and your code volition be loading on your Arduino board.

Avrdude: stk500_received: programmer is non responding? Is this some kind of joke? Who is avrdude and what does he accept against me trying to upload a sketch to my Arduino? If you lot keep getting this error when you lot're trying to upload code to your Arduino board, it can be really frustrating. I wish I could say that there was 1 single reason why this happens. Simply this error pops upwardly for many different reasons. In this video lesson, we are gonna get through a laundry listing of possible solutions to get you going. Nosotros'll start at the nearly common and easiest way to troubleshoot this and and then move upwardly on to more than detailed options. By the terminate of this lesson, avrdude should be striking the road and your lawmaking will exist loading onto your Arduino board. Stay tuned. (inspirational music)

Cheque out our membership program to learn the software and hardware skills you'll need to build your ain projects. So who is this avrdude anyhow? Well, avrdude is a utility that stands for AVR Download Uploader and when you get this error, it's caused by a generic connection fault betwixt your estimator and the Arduino and it can effect from many different things. When you see this error, information technology might feel like you've got some programming ghost living inside your Arduino IDE. But actually, information technology's but basically telling you lot hey, something is not right when I'm trying to upload code to your Arduino lath. So let'due south bound in to our list of easy things that might be able to gear up this error. All correct, the starting time one, simply disconnect and reconnect the USB cablevision that you lot're using and so endeavour uploading again. If that doesn't work, endeavor pressing the reset button on your Arduino board. And so try the upload once more. Okay, if this still isn't working, try to restarting your Arduino IDE and then see if you can upload. All correct, are you still getting the error? No worries, brand certain that you accept the correct board selected. So you lot wanna go to Tools, Board and make sure that the board at that place'south the actual one that you're trying to upload your code to. Okay, and so you know you have the right board selected only you're still getting the mistake. Okay, so you've checked the USB cablevision, you tried resetting the lath, yous've restarted the Arduino IDE, you made sure that you lot had the right board selected but yous're still getting the avrdude error. Now it's fourth dimension to make certain that you've got the correct port selected. So to find the port, you go to Tools, Series Port and y'all select the port. Now, if you don't know which i is the correct port, here's a quick way to effigy that out. So look at that port list. And then disconnect the USB cable, go to Tools, Series Port, and then see which ports are listed. Information technology could exist com4, com5, something forth that line if you lot're on a PC or USB something if y'all're on a Mac. So reconnect the USB cablevision. Now go dorsum to Tools, Serial Port and see which port has appeared that wasn't there earlier. And so that's gonna be the port that your Arduino's using. Select that port and try uploading once more. At present, if you're nonetheless getting the avrdude error, hither's the last easy thing you can effort. Brand sure that digital pins zero and 1 practice not have any parts continued, including any shields. These are the transmit and receive pins on almost Arduino boards and if you have something connected there, information technology can interfere with uploading code to your Arduino board. Now, if you have tried all of these steps and avrdude is still giving yous trouble, it'due south time for us to outset doing some troubleshooting. What nosotros're gonna try to do is isolate the issue by replacing things. The problem could exist with the figurer you lot're using, the problem could exist with the Arduino lath you're using. Or the problem might be with the USB cable that you're using. Let'south outset with the USB cablevision. Just switch it out with another one. Now, you lot might be like really? The USB cable? How probable is that? Well, you might be surprised how often these things fail. And past trying a different one, you know that yous'll have ruled that out. And so let'south say it'southward not the USB cable. Now what you'll wanna practice is check if the issue is with the computer. If you have another Arduino board handy, endeavor uploading a sketch to that other Arduino board. If you're able to upload a sketch, that tells you lot that the first Arduino lath you tried may accept the issue. Or if you have another calculator handy with your Arduino IDE installed on it, try taking the Arduino board that wouldn't upload the sketch and try uploading a sketch using that other computer. If you lot're able to upload a sketch, that might tell you the calculator'due south giving you the trouble. Then if you determine that the upshot is with the reckoner, first try reinstalling the Arduino IDE. Make sure to run through all those checks that we had at the commencement, all those easy steps. If you're still getting the avrdude error, then endeavor reinstalling the drivers. Now, if the result was with the specific Arduino lath, it gets a footling more than difficult. If you have an Arduino board where the microcontroller can come out of the board, similar an Arduino Uno, for example, make certain that that microcontroller is seated correctly. If that doesn't fix the error, you lot may need to burn the bootloader dorsum onto the microcontroller. Now, that'southward across the scope of this lesson but I'll brand sure to take a link in the clarification for you to learn how to do that. Just if those aren't working, it could be that your Arduino lath has been bricked. That is information technology's just not gonna piece of work anymore, which is unfortunate only I definitely recommend trying all the troubleshooting steps a couple more times before y'all surrender. Well, I hope one of these helped solve your problem and avrdude has left yous lonely. We'll only run through those like shooting fish in a barrel tips once more i more time. You lot wanna try disconnecting and reconnecting your USB cable. Y'all can try pressing the reset button. You can try restarting the Arduino IDE. You wanna double check that you lot've got the correct lath selected in the Arduino IDE. You wanna brand sure that you lot have the right port selected. And y'all wanna make sure digital pins nix or one, the receive and transmit pins, don't have anything connected to them, including any shields. Well, hey, I promise yous accept a fantastic twenty-four hours. Thank you a ton for watching and I expect frontwards to seeing y'all side by side time. Bye. (lively music)

And then who is this AVR dude and what is avrdude: stk500_recv() fault?

AVRDude is a utility used past the Arduino IDE. It stands for AVR Downloader Uploader and it allows you to load your lawmaking onto your Arduino lath. The avrdude: stk500_recv() fault is caused by a generic connection error between your computer and the Arduino, and tin event from many unlike issues.

Many thanks to "The Guy with The Hat" from the Arduino Stack Exchange for compiling a groovy list of fixes that we'll walk through in item here. So let's commencement with our laundry list…

Potential Fixes

Attempt disconnecting and reconnecting the USB cablevision. Yes – that simple!

Your Arduino board should have a reset button on information technology. Press the reset button and see if y'all can upload without the avrdude: stk500_recv() error.

Close the Arduino IDE, and reopen information technology once again – believe information technology or non, this can work!

Make certain you have the right Arduino board selected. In the Arduino IDE, go to Tools -> Board, and from the lists select the Arduino lath you are using.

Cheque to make certain y'all have the correct port selected. In the Arduino IDE, go to Tools -> Port and select the port corresponding to your board. (On a PC it volition start with COM, on a MAC information technology should offset with cu.usb)
- If you lot're not sure which is the correct port, simply have notation of all the ports listed, disconnect your Arduino board from the USB cable, and so cheque the port menu again. Whichever port is missing, is the port your board was Arduino was using.

The Receive (RX) and Transmit (TX) pins on the Arduino (pins 0 and 1) are used when uploading sketches on your Arduino board. If you have any connections to those pins, pull them out before you upload to the board.

If you have an Arduino shield attached to your Arduino board, remove the shield and try uploading again. This is related to the last pace, as the shield may have a circuit interfering with the transmit and receive pins.

Still getting avrdude: stk500_recv() error?

Time to start troubleshooting! If none of the easy stuff works fret! We still accept some options to try! What nosotros'll practice is try to effigy out the betoken of failure.

Information technology could exist the Arduino Board, the calculator, or the USB cable.

Test the USB Cable

Try using a different USB cable and see if you tin upload without the avrdude: stk500_recv() mistake. I know this seems similar an unlikely failure betoken, just you might be surprised how ofttimes USB cables neglect.

Exam another Arduino Board

If you have another Arduino board handy, endeavor uploading a sketch to it. If you lot get the avrdude: stk500_recv() error again, then chances are the issue is with the figurer (see Issue with Computer below).

If yous are able to upload a sketch to this other Arduino lath fine, and then it may exist the first Arduino board that is giving you the issue (see Outcome with Arduino below).

Exam a different Reckoner

If you accept some other calculator with the Arduino IDE loaded on it, try using that computer to upload a sketch to the Arduino board. Make sure you lot are trying all the troubleshooting steps higher up first if you get the avrdude: stk500_recv() error!

If you are able to upload to the Arduino, and so the issue is likely with the other estimator. (see Issue with Computer below).

If y'all get the error on this other computer, then the issue is probable with the Arduino lath (run into Issue with Arduino beneath).

Issue with Computer

Reinstall the Arduino IDE

If y'all find that the issue is with your computer, endeavour reinstalling the Arduino IDE. Information technology'southward really non that difficult. Simply get to the Arduino website, download the almost recent version of the IDE and install it once more. This doesn't affect your old sketches, which are stored in your sketchbook folder.

Reinstall Drivers

If you lot are still getting the avrdude: stk500_recv() fault, yous can check that you have all the drivers installed correctly. These should exist installed automatically when y'all install the Arduino IDE, but you tin always endeavour installing them manually. Also, if yous have an Arduino clone, sometimes those require special drivers (check the visitor that makes the boards for where you lot might find them).

Issue with Arduino:

This is where things go a petty dicey. It may be that your Arduino board is bricked (which is electronics speak for cleaved in a fashion that does not permit fixing).

Check microcontroller seated properly

If yous take an Arduino board that has a removable microcontroller chip, like the Arduino UNO, yous tin check to come across if it is seated properly on the circuit board.

Mayhap it's the Bootloader

It may be that the bootloader (a plan on the microcontroller that allows your sketches to run) is having an issue. You could burn a new bootloader on the microcontroller.

Accept a spare microcontroller?

If the failed lath in question is an Arduino with a removable microcontroller, you could always swap out another microcontroller if you have 1 handy. You'd accept to load the microcontroller with the bootloader (see previous step).
