There are __ ADC and __ PWM Pins on the Atmega328.(a) 9, 7(b) 8, 6(c) 10, 1(d) 5, 18I have been asked this question in unit test.I want to ask this question from Microcontroller Specifications topic in division AtMega Microcontroller Specifications of Arduino

Answer»

The CORRECT ANSWER is (B) 8, 6

To explain I would say: The Atmega328 has 8 ADC Pins and 6 PWM Pins, which are to be CONNECTED to the ADC that’s built in to the Arduino Uno and the PWM pins provide Pulse Width Modulated output since a digital circuit LIKE a microcontroller cannot provide a perfect analog wave.
