Arduino for Beginners - 2022 Complete Course - How Analog Pins Work

The video tutorial explains the use of analog pins on an Arduino board, detailing their default input settings and how to read values from them. It covers the conversion of voltage to integer values and clarifies the limitations of the analog write function, which cannot be used on analog pins but only on certain digital pins with PWM functionality.

How are the analog pins on the Arduino board configured by default?

• As output pins

• As input pins

• As PWM pins

• As digital pins

What integer value does the Arduino board read for a 5V input on an analog pin?

• 1023

• 512

• 2048

• 0

If an analog sensor applies 3 volts to an Arduino pin, what integer value is read?

• 307

• 512

• 768

• 640

Which function is incorrectly named for use with analog pins?

• analogRead

• analogWrite

• digitalRead

• digitalWrite

On which type of pins is the analogWrite function used?

• Only input pins

• All digital pins

• Digital pins with PWM

• Analog pins
