Several new topics have been added to the PYR website in recent months:
*Controlling Servos describes servo features and how to calibrate a servo using the CBC display, and provides example code on how to control the speed of servo motion with a ‘for’ loop.
*A brief description of variables has been added into the description of making decisions for branching and looping architectures.
*An introduction to line following tells the bacics with a simple demo robot and a single sensor example.
*A lego bumper assembly is described to extend sensing of two switches to an entire front bumper. Then a testing assignment leads the user through a experiment to measure its sensitivity.
