B
9
C
6
D
8
Explanation
In Arduino Uno, PWM (Pulse Width Modulation) pins are the ones that can generate a variable duty cycle signal, often used for controlling motors, LEDs, etc.
The PWM pins on the Arduino Uno are:
- 3, 5, 6, 9, 10, and 11.
Analysis of options:
(A) 3: This is a PWM pin.
(B) 9: This is a PWM pin.
(C) 6: This is a PWM pin.
(D) 8: This is not a PWM pin.
Correct Answer: D) 8
