Arduino Compatible Coding 13 - Displaying Custom Characters on Character LCD from Arduino

In the previous tutorial, we discussed scrolling long text strings on a character LCD using Arduino. However, it’s also possible to display custom characters on the LCD. These custom characters are user-defined and are stored in Character Generator RAM (CGRAM) of the LCD module.

The different LCD modules have different Display Data RAM (DDRAM) and CGRAM, which means several custom characters can be stored and displayed on the LCD modules.
