$!!!$ THERE SHOULDN'T BE ANY EXTERNAL LIBRARIES $!!!!$

This is an Embedded Systems lecture lab. Here is the explanation: $2-$ Program the microcontroller by using C programming on Arduino IDE. Provide the connection between your computer and Arduino board. When your program runs, it should do the following task. A$.7-$segment display will be ON at beginning. You will enter any positive integer by using Serial Port Screen of Arduino IDE. Whatever you enter, it should be displayed on $7-$segment display. If you enter a one$-$digit number, it should be shown as usual. If for example, you entered a $3-$digits number, $163,$ then $1,6$ and $3$ should be displayed on $7-$segment display with $1$ sec$.$ delay. B$.$ If you want to clear the $7-$segment display, you should enter the character $$b$.$ When cleared, $7-$segment display should be OFF. C$.$ Note that once you run the code, you should be able to try it infinitely without needing upload the program again or reset it$.$

DISPLAYING UART DATA ON $7-$SEGMENT DISPLAY

Set up the following circuit with your breadboard, Arduino$-$Uno, $7-$segment display, $220$ Omega resistors $(8),$ and jumpers.

$2-$ Program the microcontroller by using C programming on Arduino IDE. Provide the connection between your computer and Arduino board. When your program runs, it should do the following task.

A$.7-$segment display will be ON at beginning. You will enter any positive integer by using Serial Port Screen of Arduino IDE. Whatever you enter, it should be displayed on $7-$segment display. If you enter a one$-$digit number, it should be shown as usual. If for example, you entered a $3-$digits number, $163,$ then $1,6$ and $3$ should be displayed on $7-$segment display with $1$ sec $.$ delay.

B$.$ If you want to clear the $7-$segment display, you should enter the character $\text{'}$ b $\text{'}.$ When cleared, $7-$segment display should be OFF.

C$.$ Note that once you run the code, you should be able to try it infinitely without needing upload the program again or reset it$.!!!$ PLEASE NOTE THAT THERE SHOULD NOT BE ANY EXTERNAL LIBRARIES IN THE CODE $!!!$
