What will be displayed on the debug terminal?

Answer 1

28. If speed is 50, and IN7 is pushed, speed will be 45. ( This should be minimum)

29. If speed is 85, and IN8 is pushed, speed will be 90. (This should be maximum)

30. Starting speed : 65

On three consecutive presses of IN8, speed will be { 70, 75, 80 } respectively

Post that

On five consecutive presses of IN7, speed will be (75, 70,65, 60, 55 } respectively

Thus at the end of the sequence, the speed will be 55.

31.

a. Starting speed : 65

On 1 In7 press, speed will be 60.

On 9 consecutive press of IN8, speed will be respectively { 65,70,75,80,85,90,90,90,90}

Thus the variable speed will be 90.

b. speed = 0090
