Error Message Time Out When Uploading to Arduino Boarfd
One of the most annoying errors that I've faced during my projects is when my Arduino code is not uploading. Many times the reason behind each fault was different. After troubleshooting this mistake over and over, I thought to pen down my experiences and share them in a helpful post.
So, hither'south 7 reasons your Arduino code non uploading? The most common reasons your Arduino lawmaking is not uploading are:
- Errors in the connection
- Wrong port selection
- Erroneous code
- Drivers not installed
- The board needs resetting
- Presence of a brusk circuit
- Your board is drawing too much electric current
As you tin come across, the reason could exist anywhere betwixt a connection mistake in the circuit to a syntax fault in the programme. Meaning the problem your Arduino lawmaking is non uploading could be happening in the hardware or software. So, let'due south check at the reasons in detail and requite the right solution to each of these issues.
I wrote a stride-by-stride guide to upload lawmaking to Arduino, if you demand a bit more than assistance, bank check it out here: chipwired.com/uploading-code-arduino
Here'south Why The Arduino Code is not Uploading:
ane. Errors in The Connection
I of the reasons why your Arduino code might not be working is because of errors in the connection between the Arduino board and your PC.
One can use a type A/B USB cable to connect the Arduino UNO and MEGA boards via the USB port of a computer, which is OK. But, since we can apply such cables for many other applications like charging our mobiles, they can hands give an fault.
Moreover, another mistake in connection could exist due to a mistake in your calculator's USB port. If it's non working, your estimator won't recognize the Arduino board; hence, you lot won't exist able to upload your Arduino code.
Similarly, a damaged Arduino USB port could cause the same problem.
I wrote a step-by-footstep guide for uploading code to Arduino, which includes details on plugging in the right cables. Check information technology out here: chipwired.com/uploading-code-arduino/
2. Wrong Port Choice
The port number through which Arduino IDE uploads the program to the board plays a significant role. Before uploading your code, brand sure that the port number selected past your Arduino IDE matches the port number at which you connect your Arduino lath.
To do so, connect your Arduino lath to your PC and open the Arduino IDE. Then, look at the lower correct side of the window to find out at which port is Arduino connected. An example text written on the blue stripe at the bottom of the window could exist "Arduino UNO on COM17". This line indicates that your Arduino UNO board is connecting through the serial port COM17, and that'due south where the Arduino IDE should upload the code.
How to bank check if the Arduino IDE is selecting the right port?
- Click on the "Tools" carte du jour present on the top left side of the Arduino IDE window.
- In the driblet-down menu, hover over the "Ports" menu.
- And then select the port where your Arduino board is connected.
If information technology is already selected (you'll notice a small tick abreast information technology), that ways this isn't the reason why your Arduino code is not uploading.
Then, permit's movement on to the next possible problem.
3. Erroneous Lawmaking
The best lessons are the ones that y'all acquire from your mistakes. If y'all're unable to upload your code, and so yous need to check for errors in your program and right them.
Information technology's entirely OK to brand mistakes while writing an Arduino lawmaking (and any other code to be honest), then if you're i of those people who cease up with a list of errors after writing a plan, don't worry!
Arduino IDE comes with a congenital-in compiler just like many other programming platforms. This compiler is responsible for checking errors and uploading an fault-free program to your Arduino board.
After the compiler checks your programme, it will prove you the list of errors at the lesser of the screen, which you tin quickly identify and right.
four. Drivers Not Installed
Every software on your figurer needs a driver to run because it enables the operating system to communicate with that specific software. Similarly, Arduino likewise requires drivers to function correctly.
Your Arduino code might not be uploading considering of incompatible or outdated drivers or directly no drivers installed at all.
To check whether you accept the correct drivers installed on Windows, open the device manager present in the control panel of your PC. You'll find your Arduino board listed.
To update the Arduino driver to the latest version bachelor, correct-click on the name of your Arduino board and click on "update driver."
Later on updating the Arduino drivers, get back to your Arduino IDE and check if now information technology recognizes your lath through the "Tools" carte, as explained previously.
Installing the proper drivers and keeping them updated should solve this problem, and y'all'll be able to upload your code without whatsoever problem.
v. The Board Needs Resetting
Another reason why your Arduino code is non uploading might be that your board has been running for as well long and needs a interruption. All information technology needs is a push on the tiny reset button embedded in it.
If this doesn't work, then check out this interesting article showing 5 Simple Ways to Reset Arduino.
In example the reset button on your Arduino board is inaccessible (due to external shields), then y'all can try connecting a button every bit a reset button, as shown in this tutorial.
6. Presence of A Brusque Excursion
A short circuit on your board tin occur if you lot've joined the 5V pivot to the ground pin. This error commonly happens when working on a project that has too many jumper wires going here and there, i tin can hands make the mistake of connecting the power pin to the ground pin. When this happens, your PC automatically disconnects your Arduino board from the port, and therefore, you won't exist able to upload your code.
If you lot were able to upload your code earlier making those changes in your projection circuitry, then a short circuit could be the culprit behind this upload fault.
Disconnect your Arduino lath from the computer and bank check all the connections involving the 5V and GND pins. If you notice that the 5V and GND pins wee accidentally shorted, rectify the error and try uploading your code over again.
seven. Your Board Is Drawing Also Much Current
Are y'all using a heavy load in your Arduino projection? Have you calculated the maximum current requirement of your projection?
If your Arduino board is drawing more current than a computer can provide, you demand to limit your project's current requirements because the computer will automatically disconnect your board from the port whenever this happens. You won't exist able to upload your code.
And then, make sure that your Arduino is not cartoon too much electric current from your PC.

What's Next?
If y'all take successfully managed to identify the reason why your Arduino lawmaking is not uploading, then you lot must motility on to the side by side pace; troubleshooting.
In case an error in connectivity was the culprit in your example, then you need to either buy a new USB cable or repair your damaged USB port. To avert inconvenience in the future, you can buy a genuine USB cable designed specially for Arduino, from the official Arduino website. Otherwise, you tin buy it from an electronics shop, but make certain that the store offers an exchange policy in case the cable is not compatible with Arduino.
Other solutions include selecting the right port from the IDE, updating drivers, and looking for errors in your code and projection circuitry. These solutions will solve your problem and will let you to upload your lawmaking without any hassle.
A good practice is always to double-check your lawmaking and connections in your Arduino excursion.
Checking the port and drivers before y'all showtime writing your code volition also salve yous from uploading errors. Then, make certain to keep these points in mind when working on your next Arduino projection.
Happy coding!
