When the Finch's two motors move at the same speed, it moves in a straight line. When they move at different speeds, it moves in a circle.
Write a program that makes the Finch move in a circle with the left wheel at 60 and the right wheel at 15. What is the approximate radius of the circle? You may want to attach a marker to the Finch as shown in DrawBot.
Modify your program so that the left wheel moves at 60 and the right wheel moves at 50. What is the radius of the circle now?
