Robot Demo:
	Network setup
		And the raspberri pi
	Running the pi on battery
	Motor hat
	Sensors, pulse and respond
	Python programming of robots
		

A bus!
	Receiving end:
		Connect a line with a bit, by index
		For now:  Change bits one at a time
		Change all, then strobe?
	Sending end:
		We need a clock signal for this one!

Let's talk about clocks:
	Strobe
	Rising and falling edge
	Can we make a delay circuit?
	How about an iterator?
	
Back to busses:
	Can we come up with a sending end?
	Suppose it reads from a register
