In this simulation, 66 of the 100 needles crossed a line (you can count ’em). Using this number, we get a value of pi at 3.0303—which is not 3.14—but it's not terrible for just 100 needles. With ...

This goal of this project is to effectively control a weighted ball on a flat surface. Control is accomplished by the following mechanisms: A resistive 4 wire touchscreen is used to find ball position ...
