Hints:

Use two global variables to keep track of: count how many hyphens to print on each line, increment or decrement this variable

. In loop() func

tion, use a for loop to print number

of hyphens

equal to count on each line.

Use if statements to increment/decrement count and toggle variable

Troubleshoot:

Nothing prints

initialize Serial Monitor.

Software flowchart:

Write your program according to flowchart g

iven on the next page.

C/C++

count=1 total = 10 inc = true Initialize Serial Monitor i=0 Print a hyphen Ves i count Print new line NO Yes inc es true count = count-1 count = count-1 r es Count sto inc = false Yes inc=true delay for 1 Second count == 1
