This short lab will allow the student to demonstrate the use of loops in basic $C$ programming

using the ATmega$328$P microcontroller on an Arduino Uno R$3$ development platform.

Required Equipment

$1-$ Laptop with functional Geany IDE, AVR toolchain and Make environment

$1-$ Arduino Uno R$31-$ USB Type A to B Cable

Procedure

Follow the steps below in creating your program:

Create a new folder named lab$4$ in your PROG$1331$ folder. Copy your C Source

template, makefile, and prog$1331.$ h header into the new folder, then rename your C

Source file to:

"lastname$\_$firstname$\_$L$4.$c$"$

Make changes to the program flowerbox information to reflect the current file.

Ensure your template includes the AVR or C core libraries for I$/$O control, delay

functions, the standard I$/$O functions and the prog$1331.$ h header file.

The template must also include the uart$\_$init$()$ function call and connect stdin and

stdout of the stdio.h header to the UART buffer locations.

Locate the pin assignment for the on$-$board LED of the Arduino Uno. Properly configure

the associated ATmega$328$P to allow control of the LED.

Create a generic structure for one of each of the following kinds of loops in the main

program while$(1)$ loop; leave the test expressions and any other data blank for now:

a$)$ WHILE loop

b$)$ DO$...$WHILE loop

c$)$ FOR loop.

Perform the following actions in each loop:

a$)$ In the WHILE loop, create a serial print statement to print multiples of $5$ from $0$

to $100.$ Set up the conditions for the WHILE loop to execute the appropriate

number of times to accomplish this.

b$)$ In the DO$...$WHILE loop, capture up to $3$ consecutive values received from the

serial monitor $($in separate variables$).$ Print all $3$ values back to the serial monitor

once the loop completes in ASCII format.

c$)$ In the FOR loop, blink the LED on$/$off for $20$ full cycles at a speed of $4Hz.$

Send a message to the terminal indicating the program has completed. Prevent your

program from restarting after sending this message.
