## TURN THE CURSOR ON AND OFF
'''
The RPLCD library provides several functions for controlling the cursor.
You can have a block cursor, an underline cursor, or a blinking cursor. Use the following functions to set the cursor:
Blinking block cursor: 'lcd.cursor_mode = "blink"'
Line cursor: 'lcd.cursor_mode = "line"'
Cursor off: 'lcd.cursor_mode = "hide"'
The code below places a blinking cursor after the last character of text:
