## Never Ending Loop - Therefore the code will repeat forever
while True:
    led_red.value(1)    # Sets the Value of the pin to 1 - Meaning voltage is supplied to the Pin - LED Status: On

    time.sleep(0.5)     # Time.Sleep(Delay Time) - The board remains in its previous state for 0.5 seconds
   
    led_red.value(0)    # Sets the Value of the pin to 0 - Meaning no voltage is supplied to the Pin - LED Status: Off
    
    time.sleep(0.5)     # Another delay of 0.5 seconds

    ## NEXT STEPS

    # Task 1 -  Add more code to get the yellow LED to also blink after the red one 
    #        -  Find the GPIO Pin its connected to in the diagram ->
    #        -  Intialise the pin in line 7 using its pin number

    # Task 2 -  Add more code to get the green LED to also blink
    #        -  Repeat the steps above for the green LED

    # Task 3 - Modify the new code from task 2 to make all 3 LED's turn on, one after the other
    #        - Then have them all turn off and start again

    # Task 4 -  Add another blue LED to the circuit and add it to the task 3 sequence
    #        -  Click the blue plus ('+') in the Simulation window and add an LED
    #        -   Click one of the resistors and Ctrl + C & Ctrl + V to copy and paste
    #        -  Add both components to the right side of the breadboard - copying the other LEDs in the circuit
    #        -  Add a wire from a gpio pin to the breadboard
    #        -  Then add a wire from the negative terminal to a pin thats says GND (Ground Pin)
    #        -  Look at the other LEDs already set up for hints
