Answer #1

What will be the outcome for the following?
pinMode(9,OUTPUT);
analogWrite(9,63.5);
Answer:
b. A square wave generated signal with output voltage of 6.3 V.

Explanation:

pinMode(9,OUTPUT) - > set the digital pin 9 as output

analogWrite(9,63.5) -> generates square wave with voltage 6.3V

So a square wave generated with output voltage of 6.3V
