I am a teacher with a very limited understanding of the capabilities of these programs to work together.  Can Processing capture values from a simple web page and download these to an Arduino sketch? I would like students to use math operations to guide a robot through a course.  The variables would be assigned a value and students would add/subtract, etc. from it to launch the robot powered by stepper motors.  The Arduino IDE might be a little intimidating or confusing to our elementary students.  I am looking for a more child friendly method.  Your suggestions would be appreciated. Thank you .
