Now we are starting on programming the car to go along a line and stop
at the crossing for the next ride..
We had the car moving just forward.
It waited until the message came that a person was through the turnstile.
Then the car moved to the merry go round and sent a message to it to
go.
After it was done the merry go round sent a message back to the car
and it went forward again
Using this program we can get the moving and stopping to work.
Next we will modify the program to include directing which ride goes.
