ACTIVITY #2: ROAM AND AVOID SHADOWS LIKE OBJECTS
Since the photoresistor dividers behave similarly to whiskers, it’s worth examining
what’s involved in adapting RoamingWithWhiskers.bs2 so that it functions with the
photoresistor dividers.
Adapting RoamingWithWhiskers.bs2 for the Photoresistor Dividers
