1. In a ATmega328P used in Arduino UNO a).Briefly describe the function of Digital Pins 2-12. b).Are these pins for digital signal output only, digital signal input only, or both digital signal input and output? c).What are Digital Pins 0 and 1 used for? d).What is unique about Digital Pin 13?
Homework Answers
a) The digital pins 2-12 can act as either digital input or digital output pins. Out of these pins pins 3,5,6,9,10,11 act as PWM pins. Which means that these pins can give PWM signals as output if required. The duty cycle of the PWM signal is set using AnalogWrite function.
b) The digital pins 2-12 can be used used for both input and output. The operation mode of the pins are defined using pinMode function.
c) The digital pins 0 and 1 are called RX and TX respectively. TX stands for Transmission and RX stands for Receiving. These pins are used for serial communication. Both pins are a led each. Which blinks at the time of TX or RX.
d) The digital pin 13 is connected with built in led in the board.Whenever the pin 13 is high, the led will be on.When the pin is low,the led will be of.
