What is the purpose of an "if" statement in Arduino programming?

• To repeat a block of code multiple times.

• To perform a specific action if a condition is true.

• To declare variables.

• To stop the program from running.

What is the function of a "for" loop in Arduino programming?

• To check if a condition is true.

• To execute a block of code a specific number of times.

• To create a delay in the program.

• To define a new function.

Which command is used to read input from a serial monitor in Arduino?

• Serial.read()

• Serial.input()

• Input.read()

• Read.serial()

What does the "digitalWrite" function do in Arduino?

• It sets the value of a digital pin to HIGH or LOW.

• It reads the value from a digital pin.

• It creates a delay in the program.

• It initializes the serial communication.

What is the purpose of the "pinMode" function in Arduino?

• To read the value from a pin.

• To set a pin as INPUT or OUTPUT.

• To initialize the serial communication.

• To create a delay in the program.

Which function is used to send data to the serial monitor in Arduino?

• Send.serial()

• Serial.write()

• Serial.send()

• Write.serial()

What does the "delay" function do in Arduino programming?

• It checks for input from the user.

• It pauses the program for a specified amount of time.

• It repeats a block of code.

• It initializes a variable.

2. What is the syntax for a basic "if" statement in Arduino?

• if condition { // code }

• if (condition) { // code }

• if {condition} // code

• if: condition { // code }

for (int i = 0; i < 5; i++) {

Serial.println(i);

}

• It will print the numbers 0 to 4 on the Serial Monitor.

• It will print the numbers 1 to 5 on the Serial Monitor.

• It will result in an error.

• It will result in an error !

10. What is the correct way to declare a loop that runs forever?

• while (1) { // code }

• while (true) { // code }

• loop forever { // code }

• for (;;) { // code }
