Experiment 6, adapted from the SuperPro demo
For this demo, connect LEDs between B0-B1 and GND. Connect buttons between 3V and B4-B5.
Connect 10kOhm resistors between B4-B5 and GND.
Since the delay in signals being sent to/from the NXT is pretty long (10+ms in testing),
I just turned this into a demo that uses the input and output on the digital bus for
testing with the example circuit provided.
If you press the B4 button, B0 turns on, and if you press B5, B1 turns on.
