Kaitlyn_Barros 2:8085bd89612b 6 //Software Exercise 4:
Kaitlyn_Barros 0:2067ba6c5e74 7 //1. Update the software system by creating a new library, which includes
Kaitlyn_Barros 0:2067ba6c5e74 8 // a class that defines the behavior of a bouncing ball on the LCD screen.
Kaitlyn_Barros 0:2067ba6c5e74 9 //2. Demonstrate the system with two or more bouncing balls on the screen.
Kaitlyn_Barros 0:2067ba6c5e74 10 //3. Show that the system resets the ball locations when you hold the
Kaitlyn_Barros 0:2067ba6c5e74 11 // accelerometer upside down.

Kaitlyn_Barros 2:8085bd89612b 13 //Software Exercise 5:
Kaitlyn_Barros 2:8085bd89612b 14 //1. Update the ball postion using the accelerometer's data at 50Hz. Update the LCD display w/ ball postions at 11HZ.
Kaitlyn_Barros 5:5b888a1a3b98 15 //2. Use a buttom interrupt to turn data recording on/off. Use an onboard LED to indicate recording.
