A Feast for
the Sensors
We’re busting out
the sensors! Last
month, we got
acquainted with
our good friend,
the light sensor.
This time, we’ll take it a step further, learning how
to use two light sensors to accurately follow a line in
any direction. Along the way, we’ll learn about
programming logic, and once we’ve finished our
program, we’ll wrap up and lead into next month’s
focus: using data wires to create dynamic variables!
