Error for unknown reason

For some reason my code won’t upload to my arduino uno. Even when I try to upload a blank sketch it tells me it’s using too much dynamic memory or the uploading bar finishes and it just sits there at 100% not doing anything. I was trying to power the board with 8v from a DC power supply through the VIn port (I read that the VIn port is connected to the voltage regulator and needs 7-12 volts) as well as use resistors to step down the voltage to power the servo and lcd I was using. It wasn’t working so I just plugged the lcd and servo into the 5v output (which I know isn’t great for the board) to see what the issue was and my program was working but it was beginning to freak out so I unplugged everything. Then, I went to plug everything back up normally using the USB port and upload code and i was met with the “too much dynamic memory” error and it just not uploading. I reset the board and tried to upload a blank sketch and got the same two errors. Did I damage the board? I’m so confused.

Hi @400468. I'm going to ask you to provide some additional information that might provide us with information to determine the cause of the problem.

Please do this:

  1. Select File > Preferences from the Arduino IDE's menus.
  2. Check the box next to "Show verbose output during: [] compilation".
  3. Click the OK button.
  4. Select Sketch > Verify/Compile from the Arduino IDE's menus.
  5. After the compilation fails you'll see a button on the right side of the orange bar in the Arduino IDE: Copy error messages. Click that button. This copies the full output to the clipboard.
  6. Open a forum reply here by clicking the Reply button.
  7. Click the </> icon on the post composer toolbar. This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.

  8. Press Ctrl+V. This will paste the compilation output into the code block.
  9. Move the cursor outside of the code tags before you add any additional text to your reply.
  10. Click the Reply button to post the output.
