What is the range of values returned by analogRead() on Arduino?

A) 0 to 255 B) 0 to 1023 C) 0 to 5 D) 0 to 1

Write Arduino code to read a potentiometer on pin A0 and use its value to control the brightness of an LED on pin 9 using PWM:

What is the range of values for analogWrite() (PWM) on Arduino?

A) 0 to 1023 B) 0 to 255 C) 0 to 5 D) 0 to 100

The map() function can be used to convert analog sensor values to different ranges for PWM output.

True False
