Arduino practice 2

Look at the image. The right code is:

• int sensorValue = analogRead(A0);

• int sensorValue = analogRead(A4);

• digitalWrite(2, HIGH);

• analogWrite(ledPin, HIGH);

Look at the image. The right code is:

• int sensorValue = analogRead(A0);

• int sensorValue = analogRead(A4);

• digitalWrite(ledPin, HIGH);

• analogWrite(ledPin, HIGH);

Look at the image. The right code is

• int sensorValue = analogRead(A0);

• digitalRead(8, HIGH);

• digitalWrite(8, LOW);

• analogWrite(ledPin, HIGH);

Look at the image, the code:

int sensorValue = analogRead(A0);

Serial.println(sensorValue);

will print on screen:

• 5

• 1023

• 0

• 1024

Look at the image, the code:

int sensorValue = analogRead(A0);

float voltage = sensorValue * (5.0 / 1023.0);

Serial.println(voltage);

will print on screen:

• 5

• 1023

• 0

• 1024

Look at the image. A part of the code for this circuit is: (2 answers)

• pinMode(9, INPUT)

• pinMode(4, OUTPUT)

• pinMode(4, INPUT)

• pinMode(9, OUTPUT)

Look at the image. A pinMode instruction is likely to be in:

• the comments

• the loop

• the setup
