This demo shows how to use push-buttons (BTN0-3), LEDs (LD0-3), and RGB LEDs (LD4-5) on the board.
You can do the following to control the LEDs or RGB LEDs:
Button 0 pressed: RGB LEDs change color.
Button 1 pressed: LEDs shift from right to left (LD0 -> LD3).
Button 2 pressed: LEDs shift from left to right (LD3 -> LD0).
Button 3 pressed: Turns off all the LEDS and ends this demo.
