Write a function lcd$\_$rotatingBanner$(...)$ to display a rotating banner on the LCD screen. Every $300$

milliseconds $(0\mathrm{.}3$ seconds$),$ the text $$Microcontrollers are lots of fun!$$ should move one position to the

left. The banner should repeat indefinitely. Duplicate and edit the helloworld project, as it provides a

good starting point.

The program should adhere to the following requirements:

$-$ Only the first line of the LCD screen should be used. The LCD screen has $4$ lines. The second line

should be blank all the time.

$-$ At the beginning, the first letter $$M$$ should appear on the right side of line $1$ of the LCD screen. The

subsequent characters $($i$,$ then $$c$,$ etc.$)$ appear one$-$by$-$one every $0\mathrm{.}3$ seconds.

$-$ After the $20$th letter appears $($filling the first line of the LCD screen$),$ the remaining characters of the

message push the old letters off the LCD screen to the left.

$-$ After the last character $!$ appears on the right, the message continues shifting to the left. Every $0\mathrm{.}3$

seconds the leftmost letter is pushed out until the screen is completely cleared.

$-$ After the screen is cleared for $0\mathrm{.}3$ seconds, repeat the entire banner again.

$-$ The banner should repeat forever until the board is turned off

$-$ The program should be written so that only the message is modified in the code
