$3$ The function

unsigned char AnalogRead$($unsigned char pin$)$;

reads the voltage value at pin and convert the voltage to digital value from $0$ to $255$

Write a function

unsigned char CheckTemperature$($ void $)$;

$($a$)$ Call the function AnalogRead$()$ to read the voltage at analog pin A$1$ and assign the return value to a variable value;

$($b$)$ Check if value is more than $100.$ If true return $1$; and

$($c$)$ Check if value is less than or equal to $70.$ If true, return $0.$

You are to declare any variables you use.

$(5$ marks$)$

$4$ Write codes in the void setup$()$ to initialise the following:

$($a$)$ Initialise the Serial port to operate at $9600bps$;

$($b$)$ Digital pin D$5,$ D$8$ and D$11,$

$($c$)$ Wait for swo to be closed; $-$

For $1\mathrm{.}4($c$)$ you are to call the function in $1\mathrm{.}1$
