1.	There are ___ PWM pins and ____ ADC pins on the Atmega168?(a) 6, 8(b) 2, 9(c) 3, 1(d) 9, 1This question was posed to me in class test.This question is from Microcontroller Specifications in portion AtMega Microcontroller Specifications of Arduino
Answer» Right choice is (a) 6, 8 Easiest explanation: The Atmega168 has 8 ADC Pins and 6 PWM Pins. The ADC pins connect to the onboard Analog to Digital CONVERTOR of the Arduino and the PWM pins provide Pulse Width Modulated output SINCE a digital circuit like a MICROCONTROLLER cannot provide a PERFECT analog wave.
