Arduino Code C$++$

$1)$ The LCD display can show two rows of characters, $16$ characters long. Write a program which displays the letter $$f$$ in the Lower$-$Left corner $(0,1)$ of the display for $0\mathrm{.}75$ seconds and then erases the letter f$.$ Right away, the letter f should be displayed over one, that would be $(1,1).$ Again, after $0\mathrm{.}75$ seconds the f must be erased and placed over one more column $(2,1),$ for $0\mathrm{.}75$ seconds. Etc, and on down the line. When f reaches the last column, the program should repeat from the first column lower row. Only one $"$f$"$ is displayed at a time. You must use a while $()$ loop to move the letter f$.$

$2)$ Modify your program from part $1$ so that the $"$f$"$ is displayed on row $1$ and row $0$ alternately: $(0,1)$ then $(1,0)$ then $(2,1),$ then $(3,0)$ on down the line. Each time the $"$f$"$ should be displayed for $0\mathrm{.}75$ seconds, except in the last position $(15,0),$ where the $"$f$"$ should remain visible for $1\mathrm{.}5$ seconds before the display is cleared and the and the display should remain clear until the Arduino is reset.

$3)$ Modify your program from part $2$ so that now once the f reaches the last position, $(15,0),$ it becomes an $$e$$ bouncing back from $(15,1)$ to $(0,0),$ pausing for $0\mathrm{.}25$ seconds in each position. The program will then start with $"$f$"$ again.

$4)$ Modify your program from part $3$ so that the speaker plays a $200$Hz sound for $0\mathrm{.}25$ seconds when the first f is displayed, and the frequency increases by $25$ Hz for each e displayed $(200,225,250...).$ When the e$$s start displaying, the sound should keep increasing in frequency by $25$ Hz for each e displayed. The f$$s should be displayed for $0\mathrm{.}75$ seconds, and the e$$s for $0\mathrm{.}25$ seconds as in part $3.$
