3. Downloading Codes from GitHub:
  Go to the GitHub page where the codes are hosted (provide URL).
  Download the source code for the project (countdown timer, clock, stopwatch, etc.).
  Unzip the downloaded files if necessary.
4. Opening and Uploading the Code:
  Open the file of the code you want to upload in the Arduino IDE.
  Review and make any necessary modifications to the code.
  Click the 'Upload' button to load the code onto your timer.
  Once uploading is complete, disconnect the timer from the computer.
5. Testing the New Code:
  Test the features of the new code to ensure it functions as expected.
