Which of these is not a PWM pin?
A)
B)
C)
D)
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.
