Name: ___________________________ ME456 Check off Sheet Robotics v2.2! Chapter 6 Project #1 (P. 219): With your Boe-Bot’s photoresistors looking down in front of it, develop a program that makes your Boe-Bot recognize the difference between black and white. Find a large white surface and place dark-black sheets of paper on it. Hints: Make sure to test and understand what the Boe-Bot sees when it is focused on a black sheet of paper and what it sees when it is focused on a white background. Use example programs from the last three activities in this chapter. The RC decay time circuit and programs will be much more helpful for making the program work than the photoresistor divider techniques. Also, make sure this obstacle course is in a uniformly lit area. Bright sunlight from windows, and shadows cast by onlookers can make the demonstration fail.
