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
