If You're Getting an Error Message in Arduino, Let's Put You in This Article

There are many reasons for the error messages we encountered in Arduino. These problems can often be caused by communication problems between Arduino and the computer, the lack of drivers for clone Arduinos, the failure of arduino or USB ports on the computer. In addition, the user does not make the necessary settings before compilation and programming, sometimes leading to an error message. For example, you connected Arduino Nano to your computer to program it, but you indicated that you would program Arduino Uno in the Arduino IDE. As a result, it is inevitable that you will receive an error message.

Error message in Arduino
Arduino UNO

In Arduino IDE, you have done all the setup settings correctly, your Arduino has no problems communicating with your computer, but you get an error message by specifying a certain line in the IDE… This is the easiest problem to solve. You have made a typo on the line shown in the IDE. You will receive such feedback due to errors such as putting parentest in the wrong place, not putting ';' at the end of the line. However, the fact that typos are solved or no typos are made in coding does not mean that the program will work exactly as you want. For this, the algorithm you set up must be correct.

There was a problem loading arduino card or an error loading the draft

avrdude: ser_open(): can't open device ". COM1: Access is denied.
avrdude stk500_recv() programmer is not responding
avrdude stk500_getsync() attempt 1 of 10 notes in sync resp=0x01
avrdude stk500_recv() programmer is not responding
avrdude stk500_getsync() attempt 2 of 10 notes in sync resp=0x01

If you have encountered this problem, you can review its possible causes and solutions. Thus, you have overcome the port problem, driver errors and checked your card. You can also sometimes get this type of error as "an error occurred while loading the draft", I recommend trying the same solutions.

Wrong COM Port or Wrong Arduino Card May Have Been Selected

Connect your Arduino to a port of the computer. In the IDE, select the Arduino model that is connected from the Tools>Kart section. Then come to Arduino Vehicles>Port and check the connected port (Example: COM3). If the COM port is set correctly, try arduino again by plugging it into a different port on your computer.

Required Drivers May Not Be Installed

Arduino cards can sometimes fail due to driver loading. If the necessary drivers are not installed on your computer, you can solve this problem by reading our article on this page, which we explained by citing Arduino Uno as an example.

DETAIL: Is there a connection on Arduino's 0.pin (RX)?

Although this is not always a rule, sometimes you may encounter this problem when there is a connection in Arduino's 0th pin. Make sure that there is no connection to this pin during programming.

An Error Occurred During arduino compilation (Exit status 1, Error compiling for board Arduino/Genuino Uno)

If you experience this error, there is a problem compiling the program you wrote in the Arduino IDE, that is, preparing the program before it was even thrown on the card. Usually there are several reasons for this problem.

Lack of necessary libraries

You may need different libraries depending on the electronic equipment you use in the program you write. Not every library is available in the Arduino IDE. That's why you need to identify and download the libraries you need. When you transfer the library you downloaded to the C:ArduinoKuruluOlduguKonumLibrary file on your computer, you can successfully obtain it. Then you can use your library in your program by typing #include <kutuphane.h></kutuphane.h> in the first line of the program you are writing.

"Syntax" Error (Misspelling)

Maybe the problem you're facing is something much simpler. For example, syntax error, i.e. incorrect syntax… If the basic rules such as closing every parenthesis, bracket and fancy parenthesis opened, placing ';' at the end of the command, case harmony are not followed, the written program will not be compiled. Therefore, it is necessary to be careful not to make typos when writing the program. In such a case, arduino IDE can determine which line you made a mistake on, on the other hand, it indicates in the error report below.
