How to delete the code from Arduino

How can i delete the codes that i have uploaded on the Arduino. And there are certain codes i do not want and a few i want, then how can i delete the ones i don’t want.

To erase the codes, go to the “File” menu and select “New” to create a new empty sketch or you can upload a empty program or any other program.

If you want to delete specific portions of code within a sketch, you can simply remove those portions from the sketch in the Arduino IDE .

*Make sure Arduino board should connect to your computer using a USB cable.
Do let us know if it helps you.

To delete the code from an Arduino board, you can follow the steps below:

  1. Open the Arduino IDE (Integrated Development Environment) software on your computer.
  2. Connect your Arduino board to your computer using a USB cable.
  3. In the Arduino IDE, go to File > Examples > Basics > Blink. This will open the Blink example sketch.
  4. Click on the “Upload” button (the right-facing arrow) to upload the Blink sketch to the Arduino board. Wait for the upload process to complete.
  5. Once the Blink sketch is uploaded, go to File > New to create a new sketch.
  6. In the new sketch, delete all the code that is currently present in the editor.

Hey There,
As far as I get to know your question that how can you erase the uploaded code into your Arduino so here are some tips.
(1) If you’ve already uploaded the code but want to vanish it you can simply copy and paste the below code into your IDE and upload it to your Arduino
void setup() {

}

void loop() {

}
this is a blank sketch which will erase the memory of arduino and bring it back to default void.

To delete code from an Arduino board, you need to upload new code that overwrites the existing code. If there are specific parts of the code that you want to remove, you can modify the sketch to exclude those portions before uploading it to the Arduino.
Open the Arduino Integrated Development Environment (IDE) on your computer.
Open the sketch (code) that you want to modify by selecting File
You can use the IDE’s editing features to remove the unwanted lines or comment them out by adding “//” at the beginning of each line. This way, the code will be ignored during execution.
Once you have removed the unwanted part save the modified sketch
Connect your Arduino board to your computer using a USB cable.
In the Arduino IDE, select the correct board and port from the Tools menu. Choose the board model that matches the one you have, such as Arduino Uno, Arduino Nano, etc. The port selection is where your Arduino is connected to your computer.
Click on the “Upload” button (an arrow pointing to the right) or select Sketch → Upload from the menu. This will compile the modified sketch and upload it to the Arduino board.
The existing code on the Arduino board will be overwritten by the newly uploaded code, effectively deleting the unwanted parts.
the Arduino board will be running the modified code without the sections you wanted to remove.

Hey @ruchy.design
here’s the solution
To delete or remove the code that you have uploaded to an Arduino board, you can follow these steps:

  1. Open the Arduino IDE (Integrated Development Environment) on your computer.

  2. Connect the Arduino board to your computer using a USB cable.

  3. In the Arduino IDE, go to the “Tools” menu and select the appropriate board and port for your Arduino.

  4. Click on the “File” menu and select “Examples” to open the examples library.

  5. Choose any example sketch from the list that you want to upload to your Arduino (this is just a temporary step to clear the existing code).

  6. Click on the “Upload” button (right arrow symbol) to upload the example sketch to the Arduino board. This will overwrite the existing code on the board.

  7. Once the upload is complete, go to the “Sketch” menu and select “New” to open a new blank sketch.

  8. At this point, the previously uploaded code has been removed, and you can start writing or copying the new code that you want to upload to the Arduino.

  9. Write or paste the desired code into the new sketch.

  10. Click on the “Upload” button to upload the new code to the Arduino board.

By following these steps, you can delete the existing code on the Arduino and replace it with new code. Remember to save the new code in the Arduino IDE before uploading it.

If you want to keep multiple sketches on your Arduino and selectively remove some of them, you can follow the same process to upload a new sketch that overwrites the unwanted sketches. However, keep in mind that the Arduino has limited storage space, so you need to ensure that the combined size of all the sketches you want to keep does not exceed the available memory on the board.

To delete code from an Arduino board, you need to overwrite it with a new sketch or upload an empty sketch. Here’s how you can do it:

  1. Connect your Arduino board to your computer using a USB cable.
  2. Launch the Arduino IDE (Integrated Development Environment) on your computer. If you don’t have it installed, you can download it from the Arduino website (https://www.arduino.cc/en/software).
  3. Open a new sketch by clicking on “File” and then “New” in the Arduino IDE.
  4. Select all the existing code in the editor window and delete it.
  5. Verify that the board and port are correctly selected in the “Tools” menu. Choose the appropriate board model and the correct port your Arduino is connected to.
  6. Click on the “Upload” button (the right-pointing arrow) or select “Sketch” and then “Upload” from the menu. This will upload the empty sketch to your Arduino board, effectively deleting the previous code.
  7. Wait for the upload process to complete. You will see a progress bar at the bottom of the Arduino IDE, and a message indicating that the upload was successful

hope u got your answer…

To delete the code there are few steps

  1. Select all the Code and press delete button on keyboard and can write new program save it and upload it
  2. Go to “File” menu in Arduino IDE and connect Arduino to the PC then in File menu click “New”, it will open the new file and you can write new code in it , save it, and upload it

Hi , The RESET button is a white or blue push button located on top of your Arduino board . Pressing it has the same effect as disconnecting and reconnecting the power supply: The board will wait briefly for a new sketch to uploaded, then it will start executing any instructions in the sketch from the beginning.

To delete the uploaded code from an Arduino board, you need to upload a new sketch. Open the Arduino IDE, create a new empty sketch, and click on the “Upload” button. This will overwrite the existing code and replace it with the empty sketch.

To delete specific parts of the code, you can simply remove or comment out the corresponding lines or sections using double forward slashes (//) to comment out code. This will disable those portions of the code while keeping the rest intact.

After making the desired changes, save the modified sketch and upload it to the Arduino board to replace the existing code, removing the unwanted parts and incorporating the changes you made.

  1. Connect your Arduino board to your computer using a USB cable.
  2. Open the Arduino software (IDE) on your computer.
  3. Create a new sketch by clicking on “File” in the menu bar and selecting “New”.
  4. Write or copy-paste the code that you want to keep into the new sketch.
  5. Click on the “Upload” button (or the arrow icon) in the toolbar to compile and upload the new sketch to your Arduino board

Hi, @ruchy.design

To delete the code that you have uploaded to an Arduino board, you can follow these steps:

  1. Disconnect any external power source from the Arduino board and make sure it is not connected to your computer via USB.
  2. Open the Arduino IDE (Integrated Development Environment) on your computer.
  3. Connect your Arduino board to your computer using a USB cable.
  4. In the Arduino IDE, go to “File” and select “Examples” or “Sketches”, depending on your IDE version.
  5. Scroll down to find the example sketch named “Blank” or “BareMinimum”. Click on it to open the sketch.
  6. In the Arduino IDE, go to “Sketch” and select “Upload” or click on the “Upload” button (an arrow pointing to the right).
  7. The “Blank” or “BareMinimum” sketch will be uploaded to your Arduino board, replacing any previously uploaded code.

By uploading the “Blank” or “BareMinimum” sketch, you essentially overwrite the existing code on your Arduino board, effectively deleting the previously uploaded code.

If you want to delete specific sketches from your Arduino IDE that you don’t want to upload in the future, you can follow these steps:

  1. Open the Arduino IDE on your computer.
  2. In the Arduino IDE, go to “File” and select “Sketchbook”.
  3. A file explorer window will open, showing the folder where your sketches are stored.
  4. Locate the sketches you want to delete and select them.
  5. Right-click on the selected sketches and choose “Delete” or press the “Delete” key on your keyboard.
  6. Confirm the deletion when prompted.

This will remove the unwanted sketches from your Arduino IDE, ensuring that they don’t appear in the list of available sketches for uploading to your Arduino board.

Remember to be cautious when deleting code or sketches, as the process is irreversible and cannot be undone. Make sure you have backup copies of any important code before deleting it.

To delete code from an Arduino board, you typically upload an empty sketch to overwrite the existing code. Here’s how you can do it:

  1. Open the Arduino IDE:

    • Launch the Arduino Integrated Development Environment (IDE) on your computer.
  2. Connect Your Arduino:

    • Connect your Arduino board to your computer using a USB cable.
  3. Select the Correct Board and Port:

    • In the Arduino IDE, go to the “Tools” menu.
    • Under the “Board” submenu, select the appropriate Arduino board model you are using.
    • Under the “Port” submenu, select the port to which your Arduino is connected. The port should have the Arduino’s name or COM port number associated with it.
  4. Open a New Sketch:

    • Go to “File” → “New” to open a new, empty sketch.
  5. Verify and Upload:

    • Click the checkmark icon (Verify/Compile) in the Arduino IDE to compile the empty sketch. This step is necessary to ensure the code is correct and ready for upload, even though the sketch is empty.
    • After verification, click the right-arrow icon (Upload) to upload the empty sketch to your Arduino.
  6. Wait for the Upload to Complete:

    • The Arduino IDE will compile and upload the empty sketch to your board. Wait for the process to finish.
  7. Code Deletion Complete:

    • Once the empty sketch is uploaded, it effectively replaces any previously uploaded code, essentially “deleting” the old code.

Your Arduino board should now be running the empty sketch, effectively removing the previous code. If you want to confirm that there’s no code running, you can open the Serial Monitor in the Arduino IDE and see if there is no output, which indicates that the board is running an empty sketch.

Keep in mind that this method removes the code from the Arduino’s flash memory. If you want to retain the code for future use, it’s a good practice to save your code in a separate file on your computer before overwriting it with an empty sketch.

To delete code from an Arduino board, you can follow these steps:

  1. Open the Arduino IDE: Launch the Arduino IDE on your computer.
  2. Connect Your Arduino Board: Make sure your Arduino board is connected to your computer via USB.
  3. Open the Arduino Sketch: Open the Arduino sketch (code) that you want to upload to the board. This is usually done by clicking on the file with a .ino extension in the Arduino IDE.
  4. Select the Correct Board: In the Arduino IDE, go to the “Tools” menu, and under “Board,” select the type of Arduino board you are using.
  5. Select the Correct Port: In the same “Tools” menu, under “Port,” select the COM port to which your Arduino board is connected.
  6. Upload the Empty Sketch: To delete the existing code on your Arduino board, you can upload an empty sketch. Go to “File” → “Examples” → “Basic” → “BareMinimum.” This example sketch is empty and will overwrite any existing code on the board.
  7. Upload the Sketch: Click the upload button (a right-facing arrow icon) in the Arduino IDE. This will compile and upload the empty sketch to your Arduino board, effectively erasing any previously uploaded code.

After following these steps, your Arduino board will have no code running on it. If you want to upload specific code later, you can follow the same process but select the desired sketch (code) instead of the empty “BareMinimum” sketch.

Remember that uploading a new sketch will overwrite the existing one, so be sure to save any code you want to keep before uploading a new sketch.

You can delete the existing code on arduino board by uploading the bare minimum code to arduino.
void setup() {
}

void loop() {
}
}
after uploading the above code to the arduino board, the arduino board do nothing.Just like there is no code in the arduino board.
