Build the suitable circuit and write the code to build the following: - Connect 4 LEDs and a Button to the Arduino board
- Build a sequence of steps, each step on a button press

First step in sequence:
The 4 LEDs will fade-in from 0 to 255

Second step:
The 4 LEDs will fade-out from 255 to 0

3rd Step:
LED1 and LED3 will light up. (LED2 and LED4 remain OFF)

4th Step:
LED2 and LED4 will light up. (LED1 and LED3 with shutoff)

5th Step:
All LEDs will light up.

6th Step:
The LEDs will shut off one after another, by duration of 500 ms

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.
