It also just occured to me that if you want to avoid
multiplexing with external parts, the line sensor can
be doubled up with a touch sensor. If the bumper
switch is doubled up on the line sensor, it makes
sense. When the bumper switch is engaged, line
following becomes a mute point at that moment, so a
light reading would be extraneous while you are trying
to stop hitting a wall. As long as the bumper switch
is not engaged, the light sensor would read as normal.
By using range testing on the light sensor, the bumper
sense would indeed be very different light reading
value.
Anyway, its a thought
