Question $20$

SAMPLE ARDUINO CODE ANALYSIS

Debug Arduino code $-2$ parts. $($Possibly use the Arduino software you've installed? Just a

suggestion$)$

Explain what this code does in this block. Any mistakes?

digitalWrite$($ledPin$,$ LOW$)$

delay $(150)$;

digitalWrite$($ledPin$,$ HIGH$)$

delay $(150)$;

Explain what this code does in this block. Any mistakes?

int led $=9$

int bright $=0$

int amount $=5$

void setup$()\{$

pinMode$($led$,$ OUTPUT$)$;

$\}$

void loop$()\{$

analogWrite$($led$,$ bright$)$;

bright $=$ bright $+$ amount;

if bright $==0||$ bright $==255)\{$

amount $=+$amount ;

$\}$

delay$(30)$;
