Arduino with RGB LEDs and Buttons

Hi all, This's a simple school project. I have an Arduino Uno board. I have 5 lines of LED lights, each line consists of 10 LED lights. Line 1 & Line 5 are standard red LEDs, these will light up the whole time and will never turn off. Line 2, 3 & 4 are RGB and will change. The default state for RGB lines: Line 2 and 4 are green while Line 3 is red For changing the color of the RGB lines, I have 3 momentary push buttons. What I want to do is as follows: When I press button 1, Line 3 will turn green and Line 4 will turn red. When I press button 2, default state is restored. When I press button 3, Line 3 will turn green and Line 2 will turn red. Please check the photos in the attachments. And whenever there's a change in color, a small 2-pin buzzer will go off for one second, if there's no change in colors the buzzer will remain silent. All available components: Arduino Uno Breadboard Wires Resistors: 220-4.7k RGB LEDs Red LEDs Buzzer 3 Buttons I want the working code for this project, simulation results and the diagram to build it. Please feel free to ask any questions.
