How to reset the arduino pro micro

Introduction

This tutorial will guide you through the process of resetting the Arduino Pro Micro. This is particularly useful if you accidentally upload code to the Pro Micro as an Arduino Micro instead of selecting the correct target, which is the Arduino Leonardo. By following these steps, you can ensure your Pro Micro functions correctly and is ready for further programming.

Step 1: Understand the Reset Process

The first step is to understand why you might need to reset the Arduino Pro Micro. When you upload incorrect code, the board may become unresponsive or behave unexpectedly. Resetting it can restore normal functionality.

Tips

• Ensure your Pro Micro is powered on and connected to your computer.
• Have your Arduino IDE open and ready for reprogramming.

Step 2: Locate the Reset Button

Identify the physical reset button on your Arduino Pro Micro. This button is usually located near the USB port.

Practical Advice

• If you can't find the reset button, check the Pro Micro’s documentation.
• Ensure that the board is not connected to any hardware that might interfere with the reset process.

Step 3: Perform the Reset

To reset the Arduino Pro Micro, follow these steps:

1. Press and hold the reset button on the Pro Micro.
2. While holding the reset button, open the Arduino IDE.
3. Select the correct board (Arduino Leonardo) from the Tools menu.
4. Select the appropriate port where your Pro Micro is connected.
5. Click on the upload button in the Arduino IDE while still holding the reset button.
6. After a few seconds, release the reset button.

Common Pitfalls

• Releasing the reset button too early can cause the upload to fail.
• Ensure that you have the right board selected; otherwise, the upload will not work.

Step 4: Verify Upload Success

After resetting, check if the upload was successful. You can do this by:

• Observing the IDE for any error messages.
• Testing the functionality of your Pro Micro with a simple sketch (like the Blink example).

Practical Advice

• If the upload fails, try resetting again and ensure the timing when releasing the button is correct.
• Make sure to use a simple sketch for testing to avoid complications.

Conclusion

Resetting your Arduino Pro Micro is a straightforward process that can resolve issues resulting from incorrect code uploads. By following the steps outlined above, you can quickly restore your board's functionality and prepare it for future programming. If you continue to experience problems, consider checking your USB cable and connections, or reviewing your code for errors. Happy coding!
