Explanation / Answer

1.B) External Flash (program space) is where the aurdino sketch is stored.

2.D) Byte Byte is a data type with size 1byte.

3.C) Usually a Long data type is 4bytes.

4.B) Duty cycle of a PWM output varies from 0-255. For 128,it is 50% Duty cycle

5.A) pinMode(pin,Input), It will set pin to Input

6.A) string("Hi")

7.A) The setup function will only run once, after each power up or reset of the board.

8.B) if statement requires condition.

9.B) else if performs multiple tests.

10.C) (512/1024)*5=2.5V.

11.B) Serial monitor

12.D) Both of them can be used.
