Monorails and light following vehicles are being finished today.
The monorail and be programmed to wait at each station until a light is flashed.
The light follower has one motor and two light sensors.
The gear system is such that the motor going one way makes one wheel move
and going the other makes the other wheel move. The vehicle sort of walks left right left right
when you shine the light between the two light sensors.
The program for light follower works with the wires for 1 and 3 reversed and
a wait for brighter on port 3 is the first icon.
We now have batteries! Changing them fast enough is tricky.
When batteries are put in the first time the firmware needs to be loaded.
