Given the below arduino code for a blinking LED:

void setup() {

pinMode(12,OUTPUT);

}

void loop() {

digitalWrite(12,HIGH);

delay(1000);

digitalWrite(12,LOW);

delay(1000);

}

1- Modify the code so that the LED is connected to pin 4 and the delay is half second between each blinking. (15 points)

2- What happened to the led speed blinking when the delay was changed?

(5 points)

Question 3: (20 points) Watch the provided link:

Write an Arduino code to control two LEDs using a push button, given the bellow setup:

1- LED 1 is connected to pin 6

2- LED 2 is connected to pin 7

3- Button is connected to 8

Whenever the push button is pressed, LED 2 will be OFF and LED 1 will turn ON. If not pressed LED 2 will be ON and LED 1 will turn OFF.

Question 4: (20 points) Watch the provided link:

https://www.youtube.com/watch?v=9G0UFQAFWUQ&list=PLlzmd439B074hYEBYZ58mRbQ9QtpxPQ-w&index=5

Write an Arduino code to control two LEDs using two push buttons, given the bellow setup:

1- LED 1 is connected to pin 6

2- LED 2 is connected to pin 7

3- Button 1 is connected to pin 8

4- Button 2 is connected to pin 9

If both push buttons are pressed, LED 1 is ON and LED 2 is OFF. If one of the push buttons is pressed LED 2 is ON and LED 1 is OFF.

hint: you may use the if..else if statement (note: you may use other approaches)

Question 5: (20 points) Watch the provided link:

1- List the pins on Arduino that can do analog write.

2- In a PWM, given that the duty cycle is 75% what is the voltage output?

3- In a PWM, what should be the duty cycle to get a voltage output of 4 V?

4- Given the bellow Arduino command:

analogWrite( 5, 150);

a- What is the duty cycle?

b- What is the voltage output?
