Practice LED and buttons on an Arduino

In my first week, I understood the working of an Arduino and how it interacts with the components on the breadboard. The following were the stages of my work:

1. I thought of the application I wanted to achieve
2. I created a circuit diagram which showed the application in practice
3. I connected the components on a breadboard and whole connected to the Arduino
4. I wrote the relevant code on the Arduino
5. I uploaded the code to the circuit to run the application

Here are the applications I worked with:

1. Case 1: Parallel Connection of LEDs and a button to turn them on and off
2. Case 2: Series connection of the LEDs and a button to turn them on and off
3. Case 3: Parallel connection of 3 LEDs and make them glow alternatively like a traffic signal
4. Case 4: Parallel connection of 2 LEDs and make them glow alternatively with a button trigger
