Question $5(40$ marks$)$: C programming language

Write a C program that will cause the Arduino board's LEDs to turn off and on$,$ from left to left, in an infinite loop. Assuming a white circle means "LED is on$",$ and a black circle means "LED is off", then for one second the LEDs will look like:

then the LEDS look like:

then:

then:

then:

then:

and finally back to:

in a loop forever.

Recall the mapping of port bits to LEDs:

port B$,$ bit $1$

port B$.$ bit $3$

port L$,$ bit $7$

port L$.$ bit $5$

port L$,$ bit $3$

port L$,$ bit $1$

Write your answer on the page $11($opposite$).$ The C program's file has been started for you. Some marks will be given for the quality of your solution.

$($Remember: if you want a one$-$second delay, use$\_$delay$\_$ms$(1000)$; at that spot in your program.$)$
