Arduino Blink Multiple LEDs

Your mission is to create and program a circuit that has multiple blinking LEDs:

  1. has at least four LEDs wired to different Arduino pins (like 9, 10, 11, 12).
  2. has a program that makes each LED turn on and then turn off.  Like this (you can pick your own colors):

    red LED on
    red LED off
    yellow LED on
    yellow LED off
    green LED on
    green LED off
    blue LED on
    blue LED off

  3. has a comment on each line that explains what happens in that line of code. Click here for details about adding comments to a your program.   Example comment: //turn the green LED off
  4. has a comment on the first line of code that has your first and last name.
  5. name your circuit and code like this 2021LastNameBlink example: 2021MilsteadBlink
