NHD-0420D3Z-NSW-BBW-B3 Initial setting error
When power is applied to the LCD without any input, random characters are displayed one by one.
1) What is the cause of this issue? Is it because the LCD has not been properly initialized, causing random characters to appear?
2) How can this problem be solved?

Hi Jisu,
This type of issue is typically indicative of a problem with the data lines or your program's write functions. I recommend the following:
1. Verify that your jumper setting is correct for your interface selection
2. Try using our example code: Serial Interface LCD - with Arduino
3. Verify that your wiring is correct and secure with no breaks.
