Arduino quiz 2

What is the purpose of the void setup in Arduino code?

• To run the main body of the code

• To write digital signals to the Arduino

• To repeatedly loop the code

• To set things up that are connected to the Arduino

What function is used to set whether the digital pins are going to be inputs or outputs?

• pinMode

• digitalWrite

• analogRead

• delay

What is the purpose of the delay function in Arduino code?

• To create a delay in the code

• To read digital signals

• To write digital signals

• To set the pin mode

What does the digital write function do in Arduino code?

• Writes digital signals

• Sets the pin as an input

• Reads digital signals

• Creates a delay in the code

What is the purpose of the delay(1000) function in the code?

• To create a 1 millisecond delay

• To create a 10 millisecond delay

• To create a 100 millisecond delay

• To create a 1 second delay

What does the digital read function do in Arduino code?

• Reads digital signals

• Writes digital signals

• Sets the pin as an output

• Creates a delay in the code

What happens to pin 2 when the switch in the button circuit is open?

• It is connected to ground via a resistor

• It is disconnected from the circuit

• It is pulled high because it's connected to the 5 volt line

• It is pulled low because it's connected to the ground

What should be set in the void setup to read from a button connected to pin 1?

• pinMode(1, INPUT)

• pinMode(1, OUTPUT)

• pinMode(button, INPUT)

• pinMode(button, OUTPUT)

• To create a 2 millisecond delay

• To create a 200 millisecond delay

• To create a 2 second delay

• To create a 20 millisecond delay

What does the TX and RX LEDs flashing indicate when uploading the code to the Arduino board?

• Error in the code

• Board malfunction

• Successful compilation

• USB port issue
