ARDUINO HOMEWORK $1$

Question $1[50$ pts$]$:

a$)$ Create a blinking LED using Arduino Uno.

b$)$ Create a traffic light with three LEDs.

c$)$ Build a circuit using a potentiometer where, if the potentiometer output falls below a specified threshold, make an

LED blink; otherwise, keep the LED constantly on$.$

Question $2[50$ pts$]$:

a$)$ Calculate the cumulative sum of numbers ranging from $0$ to $100$ using a for loop by iteratively adding them and

display the results at each step in the Serial Monitor.

b$)$ Write a code that iterates through numbers from $100$ to $1,$ divides each number by $3,$ and displays on the Serial

Monitor only the pairs where the division results in an integer $($remainder is $0$ when dividing by $3).$ Print both the

original numbers and their corresponding results.

c$)$ Write an Arduino program that blinks an LED connected to Pin $13$ with the following conditions:

Use a for loop to make the LED blink a total of $10$ times.

Inside the loop, use an if statement to check if the loop index is an even number.

If the loop index is even, blink the LED twice in quick succession; otherwise, blink it once.

Introduce a while loop to create a short delay between each blink, ensuring the LED blinks at a moderate pace.
