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.

You can upload a blank programme or another programme or build a new empty sketch by choosing “New” from the “File” menu to remove the codes.

To erase/edit the code from the adruino,follow the steps,

1.Open Arduino IDE.
2.Connect the Ardino board to your PC.
3.Open the file you want to edit.
4.Copy the whole code to the clipboard.
5.Click file menu->Create new empty sketch.
6.Paste the whole code from clipboard.
7.Then edit/erase the code to your needs.
8.Save the new sketch.
9.Reupload the edited code/sketch to the arduino board

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
