4. If the Accelerometer Board is tilted 15 degrees past nominal, the buzzer sounds on both the
LED4 are lit. LED3 and LED4 indicate that Application Three (Freefall) is running.
Pick up the Accelerometer Board and while holding on to the board, perform a dropping motion to
simulate a freefall. A buzzer sounds on the Accelerometer Board and sends a packet to the
PC_Radio Board to indicate a freefall. The PC_Radio Board then sounds its buzzer and sets LED4.
