This week, I programmed my Hello World board with 3 LEDs and a button. I tried a few different programs, all listed below. One has the LEDs flashing in order, the other lit up an LED when the button was pressed. I had a lot of fun changing the pins and having that change which LED was illuminated. I am glad that I stuffed the board with three different LED colors, because it made it more interesting when the new pin was activated.
