Arduino Homework Week 4

Label the different parts of the code

a

b

c

d

Turn LED ON

Turn LED OFF

Create Variable

Use Variable

Label the parts of the code

a

b

c

d

Creates a variable to store mic reading

delays the code

Prints variable

Creates words on the serial monitor

What does this code do?

• Turns on the Green LED when noise is detected

• Turns on the Red LED when noise is detected

• Turns on the Blue LED when noise is detected

• Nothing

Drag and drop the options below to create the following program:
Create a program that turns the led on and off after a delay.

int ledPin = 13;

int delayTime = 1000;

VOID SETUP(){

​ (a)  

}

VOID LOOP(){

​ (b)  

​ (c)  

​ ​ (d)  

​​ (e)  

}

• pinMode(ledPin, OUTPUT);
• digitalWrite(ledPin, HIGH);
• delay(delayTime);
• digitalWrite(ledPin, LOW);

Fill in the blank:
complete the code for sending 5v to an led

_____(redPin, HIGH);

Create a variable using the options below:
​ (a)   ​ (b)   =​ 22

• INT
• tempMon
• STR
• VAR
• MONITOR

Which function is used to set the mode of a pin in an Arduino sketch?

• digitalWrite()

• analogRead()

• pinMode()

• delay()

Which function is used to give a command to a digital pin in an Arduino sketch?

• digitalWrite()

• analogRead()

• pinMode()

• delay()

Which function is used to receive information from a sensor with infinite options in an Arduino sketch?

• digitalWrite()

• analogRead()

• pinMode()

• delay()

How can PWM be programmed on an Arduino board?

• Set the pin mode to OUTPUT and write HIGH or LOW values

• Use the digitalRead() function with the pin number

• Connect the pin directly to a power source without programming

• Use the analogWrite() function in the Arduino IDE with the pin number and duty cycle value

Answer explanation

PWM can be programmed on an Arduino using the analogWrite() function, which allows you to set a pin to a specific duty cycle value, enabling control over the power delivered to devices like motors and LEDs.
