# The following line of code should be tested

# 2. To clear the display:
#lcd.clear()
# 3. To control the cursor position:
# lcd.move_to(2, 1)
# 4. To show the cursor:
# lcd.show_cursor()
# 5. To hide the cursor:
#lcd.hide_cursor()
# 6. To set the cursor to blink:
#lcd.blink_cursor_on()
# 7. To stop the cursor on blinking:
#lcd.blink_cursor_off()
# 8. To hide the currently displayed character:
#lcd.display_off()
# 9. To show the currently hidden character:
#lcd.display_on()
# 10. To turn off the backlight:
