1. Connect a push-button and a 7-segment LED to you Arduino Mega 2560. a. Wire the push button to be active low using the internal pullup resistor. b. Wire the 7-segment to a single GPIO port such that writing an 8 bit value to the port will result in a particular character being displayed on the 7-segment. 2. Write a program to increment your 7-segment display by one character each time the button is pressed. a. The 7-seg initially shows 0. b. Press button once c. The 7-seg shows 1 d. Press button again e. The 7-seg shows 2, and so on. 3. It rolls-over from F back to 0. a. Make sure your program properly denounces the signal such that the display only increments once for each button press. b. The value increments after the finger is taken off the button

Describe in pseudocode an algorithm that given an integer n and a linked list of elements increases the linked list by a factor of n by replacing each element in the original list with n copies of that element. for example, if l: [18, 7, 4, 24, 11] and n = 3 the resulting list should be l: [18, 18, 18, 7, 7, 7, 4, 4, 4, 24, 24, 24, 11, 11, 11]. if the value of n is less than or equal to 0, the list should be empty after the call. what’s the running time of your algorithm?

In a compound condition, both conditions on either side of the logical operator and must be true for the overall condition to be true. a: true b: false

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called. write a constructor for the above class that initialized both variables to zero. write a tostring to display both the tank and speed when the car is printed. modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter. write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
